I. INTRODUCTORY
I. 0. We aim in this paper to study some grammatical rules which underlie the
•sentence structures of English.
I. 1. When a native speaker of English hears two utterances and judges the one is
English and the other is not, we say that he has an ablility of judging some utterancesto be genuine utterances of his own language. We call his ability of judgement a native
speaker's intuition. In other words, we may say that he knows grammatical rules of
English, because only by his intuition we can test the adequacy of a grammar proposed
for English.
I. 2. The fundamental aim, Chomsky says, in the linguistic analysis of a language
L is to separate the grammatical sequences which are the sentences of L from the
ungrammatical sequences which are not the sentences of L and to study the structure
of the grammatical sequences.1 We shall consider briefly the substance of a grammar
before taking up grammatical rules. According to Bach,2 the linguist begins his study
by segmenting the stream of speech into discrete units of sound. And he continues,
"In fact, this attempt has occupied the energies of linguists over the last few decades

and led to a theory of representation called phonemics. Because phonology is closely
related to the physical side of speech, it is easy to fall into the error of imagining thatphonology is somehow more "objective" or sure than the other parts of linguistic study."
But when we intend to consider the internal states of langaage, these operations such
as segmentation and classification are of no use, for we cannot reveal grammatical
features, given only the phonetic form of speech. Segmentation and classification of
utterances are only the first task of the linguists. Grammar is not a mere description
of physical events but a subject of theory. What we must account for is that certain
sequences are in the language—say, on the rules of the language—and the others are
not.
I. 3. We argued above that the grammar is a subject of theory and it cannot be
revealed by merely stating the observable phonetic forms. For instance, the following
sentence;
The shooting of hunters occurred yesterday.
is a grammatical one in English. But it has two meanings in spite of showing only one
(phonetic) form. This means that in this sentence structure there are two sentence-
formation processes as the following ;
( a ) Hunters shoot something.
( b ) Someone shoots hunters.
and these two sources, (a) and (b), were transformed respectively. After this process,
the sentence;
The shooting of hunters occurred yesterday.
has been generated. This generative process exists in the mind of a native speaker,
therefore he can understand this sentence. This means that he knows rules of his
language completely. As the example above shows, an internal state of language cannot
be explained easily by mere representations of phonetic forms only. If we intend to
reveal the sentence structures by means of merely observable phonetic forms, we will
soon find the limitations of this approach and miss the most important fact, say, gene-
rative process of the sentence structures. We do not deny the importance of the study
of speech sound which is just outside one end of language. But how much we may
study these events, we cannot understand internal states or workings of language. We
also cannot use a language without intellectual capacity which gives phonetic forms of
language deep meanings. This capacity is within the mind of ours. The working of
language is not a physical process but it is based on something more intellectual.3
After we have obtained the ability of using the rules of language, we can comprehend
3 Accordingly, the definition of Bloch-Trager's, "A language is a system of arbitrary vocal symbolsby means of which a social group cooperates." is quite an unsatisfactory one, because it emphasizestoo much upon the physical phenomenon, but ignores a native speaker's intuitwn.

1942), p. 5.

the workings of language,
I. 4. So far, we have discussed that the workings of language cannot be revealed
by mere physical processes. Next, we shall demonstrate that a sentence is not a mere
arrangement of morphemes or words. If sentence structures were made clear by
observing an arrangement of morphemes, the 1C analysis of sentence structures would
offer more clear-cut results. For instance, if we analyze the following phrases;
( 1 ) the growling of lion( 2 ) the raising of flowers,
the result of the 1C analysis of the two phrases is the same like T-N-P-N. This
example shows that the two phrases are analyzed as having the same class-construction,
and we miss the important fact between the two sentences. That is to say, we cannot
make explicit the difference between the two sentences by adopting the analysis like
that,
I. 5. The result above shows that the sentence structures are not revealed by
observing merely an arrangement of \vords and analyzing the sentence into the immediate
constituents. The sentence structures shown as the example above have quite deeper
structures. Some sentences have the same structure even though they are composed
of totally different forms. Some sentences are understood in a certain way parallel to
other sentences of a different structure. Some sentences are related in a definite way
to certain other sentences. Some sentences are ambiguous, and so on.4 These facts
should be explained by a linguistic theory. There are two layers in the sentence
structures. They are surface structures such as phonetic forms, and deep structures.
Grammar must describe deep structures. What we wish to reveal is deep structures of
sentences. A grammar of the language L is essentially a theory of L." The com-
plete theory will offer grammatical rules and explain structural relations between sen-
tences. To describe sentence structures correctly, we should consider the process of
generating sentences, and describe in the shape of grammatical rules. This is an app-
roach to sentence structures. In the following chapters, we shall study phrase-structure
rules and transformational rules of English.
II. PHRASE-STRUCTURE RULES
II. 0. Introduction
English is not a finite state language. Thus it shows all the characteristics which a
natural language contains. First, in Eglish, not all sequences of the elements are
permitted. Hence a theory about English cannot be a mere list of the elements; we
must show how these elements are combined into sentences. Second, the sentences of
English are finite in length, but its members are infinite. Therefore, English is not
explained by a simple theory of linguistic structure based on 'Markov process models'

and the like. Although we stated above that English is infinite sets of sentences, a
grammar of the form illustrated will, however, generate only a finite number of terminal
strings. Thus, the restriction that a grammar should meet is recnr&iveness. This is
an important conception of a grammar. We shall study in this chapter a more po-
werful theory what we call Phrase-Structure Rules, considering conditions of this gram-
mar.
II. 1. Some Basic Notions from Chomsky
Here we shall only introduce Chomsky's notions. Chomsky defines his model for a
constituent structure grammar in the following passage.1
"A particular simple assumption about the form of grammars'"would be that each
rule be an instruction of the form rewrite </> as <p (symbolically, ^-»^), where ^ and <p
are strings of symbols. Given such a grammar, we say the tf1 follows for a if (T = • • • <f>
... and ffl = • •• </>••• (that is, if a1 results from substitution of </> for a certain occurrence
of <1> in <r), where </> -> </> is a rule of grammar, we say that a sequence of strings a\,
•••, o-i, is a (A-DERIVATION if </>=ai and for each i, tf,-+i follows from ff,. A (A-derivation
is TERMINATED if its final line contains no substring X such that X—>-w' is a rule.In particular, we will be interested in terminated S S j? derivations ; that is, terminated
derivations that begin with the string S S S. Suppose that each syntactic rule <p—></'
meets the additional condition that there is a single symbol A and a non-null string
w/ such that i^XiAXa and </>=Xi\v /Xa. This rule thus asserts that A can be rewritten
w/ (i. e., w/ is of type A) when in the context Xi—Xa, where Xi or Xa may, of
course, be mull. A set of rules meeting this condition I will call a CONSTITUENTSTRUCTURE GRAMMAR. If in each rule <f>->^, <js is a single symbol, the grammar(and each rule) will be called CONTEXT-FREE; otherwise, CONTEXT-RESTRICTED."2
II. 2. Immediate Constituents and Phrase Markers
The notion of immediate constituents is quite traditional. It is based on the belief
that segmentation and classification of utterances can reveal the sentence structures of
a languafe. Thus Chomsky says ;
Customarily, linguistic description on the syntactic level is formulated in terms of
constituent analysis (parsing). We now ask what form of grammar is presupposed
by description of this sort.3
And, if we are given a sentence like;
( I ) The man hit the ball.we find that the sentence as a whole consists of two parts, The man and hit the ball.
The man in turn consists of The and man ; hit the ball consists of two parts hit and
the ball, and finally the and ball. Ultimately, the sentence consists of as the following

discrete elements, The, man, hit, the and ball. And a more adequate analysis would
be
The man hit the ball
This cafcegorization is what we call 1C analysis. But this categorization is inadequateunless it is associated with labellinig.-* In order to represent the labelling which can
show the grammatical relations of elements, we write the following diagram,
Diagram ( 1)
Sentence
NP VP
N NP
the man
N
hit the ball
We shall call such representations as Diagram ( 1 ) 'Phrase Markers' (P-markers).
Since it is natural to consider that each sentence has at least one P-marker5, we can
write another P-marker, given a sentence like ( 2 ) ;
( 2 ) A boy likes the girl.and we compare these two P-markers and judge certain elements belong to the same
class and some do not. Postal explains as;
The fundamental notion in the P-markers is that certain strings of elements are related
to certain other single elements by the relation 'is a (mamber of the category)'."
Thus, in Diagram ( 2 ),
Diagram ( 2 )
Concerning the labelling, Postal states in Constituent Strnctwe, p. 7 ; "the labelling is necessary,if for no other reason, in order to represent correctly the similarities and differences of elementsin different sentences and different parts of sentences."About the coHstructional homonymity, see Bach's Introduction to Tranfsormational Grammars, p. 40.Paul Postal, Constituent Structure: A Study of Comporary Models of Syntactic Description, (Indiana :The Hague, 1964), p. 7.
— 75 —
B c
we can represent this relation, say 'is a', as the following. Elements B and C are traceable
back to A, so that these elements are said to be an A, or to be constituent of A. A
is said to dominate such strings B and C. Consequently in Diagram ( 1), (NP-VP)is a sentence, and so on.
As explained above, a proper P-marker (when represented in a labelled tree diagram)
IS
a topological structure of lines and nodes comforming to the general requirement
that a unique path be traceable from the termination of every branch to the point
of origin of the whole tree ••••••7
And these diagram shown below are not permitted as a proper P-marker.8

Diagram ( 4 )
Diagram ( 5 )
P-markers surely can tell us the grammatical category of words and phrases, but
cannot tell us more. That is to say, the grammatical description of a language cannot
be a mere list of P-markers, But we think it not fruitless to study the principles
which generate the P-markers like above. Next we study what restrictions must be
placed on PS rules,

II. 3. Restrictions on Phrase-Structure Rules
Phrase-structure (PS) rules are of the form X-
tions.
( 1 ) They are string-replacement rules (symbolically a-
( 2 ) They are expansion rules (symbolically a—^b+c).( 3 ) No rules of the form a+b—>b+a are permitted.
( 4 ) No rule of the form a—>a+b may be used.
Restriction ( 1) can be shown as;Diagram ( 6 )
x
Y and obey the following restric-
»b).
Restriction ( 2 ) ;If there were in a rule,
C + A—>hit + the + ball
then there would appear in a derivation succeeding lines containing the segments
A+C+AA+hit+the+ball.
If such were the case, then there would be two ways of relating the lines ;
Diagram ( 7 )
C A
hit the ball
or,
Diagram ( 8 )
A
hit/
the ball
in such a derivation, it is impossible to construct a proper P-marker. This is the
reason why restriction ( 2 ) is needed in PS grammBr,
Restriction ( 3 ) ;Regarding to restriction, ( 3 ), Postal states as the following ;
the P-markers which result from permutations cannot correctly represent language
structures because the asymmetry of the relation 'is a(n)' is not preserved. That
is, this relation must hold between, say Noun and NP but not NP and Noun.9

and he explains this restriction using the following instances. The sentences like John
will come and will John come are to be derived by ordered rules which are;
S—>Noun+VerbVerb—>Modal+VNoun—>-Modal in Modal
Modal—Woun in ModalNoun—> JohnModal—>will
V—>comeThen the sentence will John come will receive the P-marker ;
Diagram ( 9 )
Noun
will
Modal Modal
John come
As Postal says, the categorization in Diagram ( 9 ) is linguistically absurd. This is thesame to say that John is similar to will and mill is similar to boy, teacher, chalk, etc.Thus whenever permutation a+b—>b+a occurrs, there will be much confusions in PS
grammar.
Restriction ( 4 ) ;Finally, restriction ( 4 ) states there must not be rules which change an element into
itself plus another element. If there is a rule A—>A+B in a derivation to the left of
an element C;
A+CA+B+C
we cannot judge whether B is derived from A or from C.
II. 4. Some Examples of Rewrite Bales and Derivation
In this section, we shall follow the instruction 'rewrite X as Y' and constitute the
grammar of some English sentences. At the beginning, let us suppose the following
simple grammar.
Gi Sentence
rl Sentence—>NP + VP
r2 NP—>T+Nr3 VP—>Verb+NP

9 the+cat+caught+the+N
10 the+cat+caught+the+ratWe shall call Di a derivation of the sentence The cat caughi the rat. If the lastline of the derivation cannot be rewritten by the rules of Gi, we call the line a terminal
string (in this case, the+cat+caught + the + rat), and its symbols are called terminalsymbols. Other symbols are non-terminal. Thus, a derivation is a sequence of lines
beginning with Sentence, each obtained from the preceding by application of one and
only one rule to a single element.10
Now we can write the derivation of (Di) as the following P-marker;

But in the grammar (Gi),Now, then, let us consider a more complete type of grammar. We shall take up the
subject-predicate form again."

Ri S—>NP+VPSince NP occurrs as a high order constituent of the predicate, objects of transitive verbs

first. Moerover, VP develops sentence patterns in various ways as He runs very fast
or He runs a farm.

part of the predicate, i. e., the finite verb and its modifiers, objects, etc.

Thus the P-marker is as the following ;

Thus the 'John + pres + be + Ing + write+a+letter' is a proper terminal string of thederivation. We cannot rewrite its symbols further. If we intend to make progress,
much confusion would occur. That is to say, PS grammar would be more complicated
and clumsy one.
II. 5. Some Inadeeuacies in PS Rules
The rules for the phrase-structure of English point up several difficulties in a grammar
conforming to the adopted restrictions. As shown in II. 4, one of the difficulties is the
treatment of the verbal auxiliaries and we recognize that the treatment is beyond the
scope of PS rules. Clearly something besides PS rules must be included in an efficient
grammatical theory. Before going on this theory, let us note some of the inadequacies
of a phrase structure grammar.
First, let us suppose the following two sentences ;12
( a ) What are you looking for ?( b ) What are you running for ?
12 Robert B. Lees, "Review of Syntactic Structures," Language, 33, (1957).
— 81 —
Masakatsu Hata
These two sentences have different sturctures. If we use the simple paraphrase, (a)
contains prepositional phrase for what and (b) contains an interrogative ivhat for
(=====why), but we have no mechanism for associating a sentence with its paraphrase.
Then, the two sentences appear to have identical constituent structures. Secondly, as
we stated in I. 2, there are many instances of sentences which are ambiguous in the
level of the phrase-structure grammar. The sentence below can be justified as having
only one single analysis. Thus the sentences;
The stooting of hunters occurred yesterday, is understood in two ways;
( a ) Hunters shoot something.
( b ) Someone shoot hunters.
There is no way, however, for assigning two different immediate constituent analysis
and there is no word in the sentence which may be said to have two different lexical
meanings, and it is more important that we have no way how to account for its
ambiguity in the phrase-structure grammar. Aud finally, we have no way to show
the following sentences are related each other;
( a ) John hit hill.( b ) Bill was hit by John.
though they show a different constituent structure. And though the sentences;
( a ) John hit Bill.
( b ) Bill hit Jdhn.are not related each other, we analyze them as having the same structure.
III. GRAMMATICAL TRANSFORMATIONS
III. 0. Introduction ; Transformations
Here we shall consider a transformational (T) rule to be a rule of the form ;
X—>YIn PS rules, X and Y stand for single strings, but this time they do not represent
single strings. Thus Bach states as the following;
a transformation is a rule which requires us or allows us to perform certain changes
in the terminal strings of the PS grammar is, and only if the string nas a certain
structure. This structure must be precisely what is represented in the P-marker
of this string as derived in a certain way from a particular set of rules.1
As we have seen in chapter II, PS rules could not provide us a mechanism how to
analyze sentences successfully. But T rules are believed to provide us a powerful tool
for deciding how to analyze sentences.
We state transformational rules in the following way. Each rule must be marked
E. Bach, An I'ntrocliiction to Transformational Grammars, p. 60. Similary H. A. Gleason states asthe following: "A transformation is a statement of the structural relation of a pair of constructionswhich treats that relation as though it were a process." An Introduction to Descriptive Lwguistics,(Revised ecl.; New York : Holt, Rinehart and Winston, 1961), p. 172.
— 82 —

as either optional or obligatory. The first part of the rule is a structural description(SD) which specifies the class of strings to which the rules apply. Thus let us takethe sentence Bill hit John and state a SD of the sentence. The P-marker of the
sentence is as the following ;
Diagram (12)
N'P VP
Np,o,,
Bin
Aux
Tns
MV
prop
Johnpast hit
SD might be as the following;SD: NP-Aux-V-NP
The second part of the rule specifies the strnctitral change (SC), The operation is as
the following;
SD: NP - Aux - V - NP
i iSC: Xi -
IX, -
iXa - X..
Then let us consider the passive transformation.2
Passive optional
SD: NP - Aux - V - NP
SC : Xl — Xa — Xa — X.i
X< - Xs +be+ En- X3 - by+ Xi
Thus 'Bill+past+hit+John' may be transformed into the passive transformation;
John+past+be+En+hit+by+BillThe product of a transformation is referred to as a transform.
As well known by the examples, the relation between PS rules and T rules are quite
interesting. PS rules must be set up in such a way that such and such a string will
undergo such and such a transformation.
Further it is possible to conceive that a transformation has a power of explaining the
relations between structures.
Thus it explains similar connections between John is writing a letter and any of the
following sentences.
N. Chomsky, Syntactic Structures.
— 83 —
Masakatsu Hata
Who is writing a letter ?Is John writing a letter?
What is John writing ?John is writing a letter, isn't he?
The most interesting characteristic of T rules is that'they can apply to already trans-
formed structures. Examples are the following;
John hit Bill.
iBill was hit by John.
iWho was hit by John?
iWas Bill hit by John ?
iBill was hit by John, wasn't he?
III. 1. Kernel Sentences
In the preceeding chapter, we studied some grammatical rules in PS grammar. That
is, we followed the rewrite rule and obtained the following terminal strings by a step-
by-step presentations of a set of rules;
( 1 ) John + pres + be + Ing + write + a + letter
And we also pointed out this step was the limitation of PS grammar so far as we were
concerned this grammar. If we intend to make the germinal string to be a appropriate
form, we must add at least the following rules;
Pi, Af==En, Ing, Tns, ••••••
Rig v====M, have, be, Verb
Ru, Af+v—>v+Af
But this rule cannot be permitted in PS grammar, so that we set up an auxiliary
transformation rule.
T,,,,: X-Af-v-Y—>.X-v®Af-Y.3
Thus our terminal string becomes ;
( 2 ) John + be + pres + write + Ing + a + letter
(Taux-two times)
Further, to make ( 2 ) a perfect form, we had better consider a word boundary instead
of a concatenation sign. Thus let us add the following word-boundary transformation.
T,,,b: X-Y=XSY
The effect of the rule is;
( 3 ) S John S be ® pres i? write ® Ing ji a S letter S
© denotes an affix-juncture : see Lees' The Grammar of English Nominaliwtions, p. 48.
84
A Study on Some Grammatical Rules in the theory of Generative Grammar
The morphophonemic rule will convert ( 3 ) into ;
( 4 ) John is writing a letter.'*
The sentence like ( 4 ) is called a kernel sentence. Kernel sentences are defined as
the following by Bach:
Sentences which are derived from terminal strings by the application of obligatorytransformations only and phonological rules are called kernel sentences."
It the kernel sentences are applied by a sequence of one or more transformations, we
can generate many and more complex types of sentences." Examples are given by
Harris.7
Si Mary has a sad fate.
Sa Mary's fate is sad.
Sa Mary's fate is a sad one.
S< Mary's is a sad fate.
These are transformed from some or all of three kernel sentences!
Ki Mary has a fate.
Ks Fate is a fate.
Kg Fate is sad.
The following transformations are involved.
For Si : Kg overlap with Ki
For S-2 : Ki N has N's, overlap with K:i.
For 83 : Ki N has N—>N's N, overlap with Ka (first N) ;Ka Pro-N of second N;
Kg overlap with Ka (second N).
For Si : Ki N has N—>N's N overlap with Ka (first N) ;K..J Zero recurrence of first N;
Ka overlap with Kz (second) N.
Thus the setting up the kernel sentences is an important role for a generative gram-
mar.
III. 2. Types of T Rules
As we have studied in II. 3, PS rules contain only two grammatical operations, namely
they are string replacement rules (a—>b) and expansion rules (a—>b+c). But T
rules can carry out not only these operations but also the other grammatical operations.
These operations which are not permitted in PS grammar will be listed below.
' We shall not treat the morphophonemic rule in this study.6 An Introducion to T'ransformational Grammars, p, 69." Harris says, "Transformations have some particular effects in the over-all structures of the language.
They make possible an unbounded variety and length of sentences out of the stock of kernelsentences, thanks to the unbounded repeatability of various sequential transformations. They givean organized view of complex sentences." ; Co-occurrence and Transformation in LinguisticStructure", Language, 33, 283-340, (1957).

1 A deletion rule (symbolically a+b—>b)
2 A reduction rule (symbolically a+b—>c)3 An addition rule (symbolically a—>a+b)
4 A permutation rule (symbolically a+b—>b+a)
The characteristic of T rules is that they may perform any of the six rules in anycombination.
We shall classify T rules into six types. Before listing each type of them, let us
consider the major differnce between PS rules and T rules. As an example, we shall
take up a replacement rule (a—>b). Suppose that we have the following P-marker ;
Diagram (13)
x
then, if we follow the PS rule a-
Diagram (14)
a c
•b, the resulting P-marker will be as the following ;
This fact shows that PS rules apply only to a simple string. On the other hand T
rules may be regarded as applying to P-markers rather than simple strings.
Therefore, if we apply a T rule a—>b to the P-marker described above, the result
will be shown as follows.

III. 3. Some T Rules for English8
In the beginning, let us suppose the following terminal string which is derived byPS rules.
( 1 ) John + pres + have + En + write + a + letterTo make this string pronounceable, we must set up rules as the following.
Af===En, Ing, Tns (Tns—> <fPres]>)Lpastj
v====M, have, be, V---"-
sX,
zXa-
zX.,
>x,
(A) X-Af-v-Y—>X-v+Af-Y
(B) X-Y—>X?Y (X+v or, Y+Af)We call (A) an auxiliary transformational rule (henceforth Tuux) and (B) a wordboundary transformational rule (henceforth Twb). Both of them are obligatory T rules.
Thus ( 1) is applied by Taiix ;
( 2 ) John + have @ p res + write ® En+a+letter(Taiix-two times)
then applied by T,vb ;
( 3) <? John j? have ® pres S write ® En S a S letter {?Ultimately the morphonemic rules will convert this line of derivation into;
( 4 ) John has written a letter
in phonemic transcription.
These rules, as the examples shown above, play an important rule in a transformational
grammar.
Now let us consider the rule which generates the sentence
( 5 ) John hasn't written a letter.
In this section we shall follow Chomsky's approach, accordingly most of the examples are takenfrom Chomsky's Synlacdc Structures, especially pp. 61-84.

The rule which makes a negation introduces not or n'i into the auxiliary verb phrase.
Henceforth we shall state this rule as Tnoi. In the case of a negation, not or n't must
be introduced immediately after the second morpheme of the auxiliary phrase if the
phrase contains at least two morphemes. If the phrase contains only one morpheme,
T,,ot introduces not or n't just after the morpheme. But T,n,i must be applied before
Taux. Thus Tnnt operates on the string;
(6) John+pres+have+En+write+a+letterand gives
( 7 ) John+pres+have+n't+En+write+a+letter(Ultimately, John hasn't written a letter.)
Next, let us consider how Tuot operates on the following string;
( 8 ) John + pres 4- write + a + letter
we can write;
( q ) John+pres+n't+write+a+letterBut we defined Tnoi should be applied before Taux, and this string does not contain a
sequence Af+v. So that we must add to the grammar the following obligatory T rule
which applies after Taux and T,,.i>;
X S Af S Y—>X S do © Af S YWe shall call the rule above Tdo. Thus ( 9 ) becomes
(10) S John f, do © pres+n't j? write S a » letter S(Ultimately, John doesn't write a letter.)
Thus we can formulate Tnot as the following;
Tnot—optional
fNP-Tns-V.--..-
iNP-Tns+M-----.-SD : {
NP-Tns+have-••••••
(.NP-Tns+be-••••••
SC : Xi-Xa-Xa—>Xi-X2+n'fc-X3
Next we shall consider the class of 'Yes-or-No' questions such as 'has John written
a letter' 'can John write a letter' 'did John write a letter'. This time we set up Tq which
operates on strings that are analyzed into three segments in one of the following ways ;
NP-Tns-V-----'
NP-Tns+M-----..
NP-Tns+have--.....
NP-Tns+be-••••••
Notice these strings are just the same as in the case of T,,oi. T,| has the effect of
interchanging the first segment and the second segment of these strings. The requirement
That Tq should meet is that it applies after'pres}
Tns-past;

(11) ( i ) John—pres—write+a+letter( ii ) John — pres + can - write + a + letter
(iii) John—pret+have-En + write+a+letter(iv ) John — pres + be — In g + write + a + letter
'pres(By Tns—»•<;'"_"';>)
jiastjThen we apply Tq ;
(12) (i) pres-John—write+a+letter( ii ) pres + can — John - write + a + letter
(iii) pres+ have — John — En + write + a + letter(iv ) pres + be — John — Ing+ write + a + letter
Next we apply Tnux and Tao;
(13) ( i ) ff do ® pres ff John <? write ff a » letter j?( ii ) S can CD pres S John S write ff a ff letter {?(iii) S have ® pres {? John S write ® Enff a ff letter S(iv ) <? be ® pres {? John S write ® Ing j? a S letter S
Ultimatly applying morphonemic rules, we derive;
(14) ( i ) does John write a letter(ii) can John write a lefcter(iii) has John written a letter(iv) is John writing a letter
in phonemic transcription.
If we apply Taiix and T,vb to (11) and don't apply Tq, we may derive the following
sentences;
(15) ( i ) John writes a letter( ii) John candwrite a letter(iii) John has written a letter
(iv) John is writing a letterThus (13 i-iv) are the interogative counterparts to (15 i-iv). As the examples have
shown, "Transformational analysis brings out the fact that negatives and interogatives
have fundamentally the same 'structure".9
Fourthly, we shall take up the problem of irregular behavior of 'have'. The terminal
string which underlies the kernel sentence 'John has a book' is as the following;
(16) John+pres+have+a+bookIn this case 'have' is a fimite verb and not an auxiliary verb. Now let us consider
how T,,ot and Tq operate on the terminal string (16). Tnoi applies to the string ;
NP-Tns-V--NP-Tns+have-••••••
9 N. Chnmsky, Syntaclic Structures, p. 64.

Masakatsu Hata
But (16) contains the both structural descriptions. Hence if we apply Tnoi to (16),
the results may be ;
(17) (i) John-pres+n't-have+a+book( ii ) John — pres + have + n't— a + book
applying T,vi, to (17 i)
(18) ( i ) John—do+pres+n't—have 4-abook
(Ultimately, John doesn't have a book.)
applying Taiix to (17 ii)
(18) (ii) John—have+pres+n't—a + book(Ultimately, John hasm't a book.)
Similary, if we apply Tq on (16), the results may be;
(19) ( i ) does John have a book( ii) has John a book
But in the case of the other verbs except 'be', such forms as (18 ii) and (19 ii) are
impossible. Thus we can say 'have you a book ?' and cannot say 'read you a book ?'
This difference can be explained as the following ; 'have you a book' is derived from a
kernel sentence 'you have a book' by applying Tq, bufc even if we apply Tq to a kernel
sentence 'you read a book ', we cannot derive 'read you a book' from the kernel
sentence. This means that the difference between two sentences is decided whether
they are generated from the kernel sentences by any transformational rules or not.
And if we consider the following P-marker;

We can not write ;
(20) ( i ) John—pres—have + En + write 4-a + letter
but(20) (ii) John-pres+have-En + write+a+letter
The reason is explained by showing that 'have' can not be traceable back to a node V.

A Study on Some Grammatical Rules in the theory of Generative Grammar
By this fact, the un-grammatical10 sentence 'John doesn't have written a letter' can not
be derived. Now let us take up another types of interogatives. That is to say, we
shall set up a ne\v rule which can generate the following sentences.
(21) ( i ) What did John write?(ii ) Who wrote a letter ?
These sentences, of course, do not receive Yes—or—No answers.
The terminal string underlies (21 i) and (21 ii) is ;
(22) John -Tns- write +a+ letter
To generate (21 i) and (21 ii) we must set up a new optional transformation Tw.
Concerning T,y, Chomsky explains as in the following;
T,y operates on any string of the form X—NP—Y where X and Y stand for any
string (including, in particular, the 'null' string-i. e., the first or third position may
be empty) T,v then operates in two steps. ( i ) Twi converts the string of the form
X—NP—Y into the corresponding string of the form NP—X—Y; i. e., it inverts
the first and second segments of X—NP—Y. It has the same transformational
effects as Tq. (ii) Twz converts the resulting string NP-X—Y into who—X—Y
if NP is an animate NP or into what-X-Y if NP is inanimate.""
Moerover he adds the requirement that T,, can apply only to which Tq has already
applied. Thus the order of applying the rules to the terminal string which underlies
(20 i) and (20 ii) is;
Tns—> jpres{ =^ T, ==> T,,i ==^ T,.. =^^ '}.pasd ' " ' ^_^_,-_^ ' ^Tdo
w
==^ TW b :==^' Morphophophonemic rules
For example, the terminal string
(22) John-Tns-write+a+letter
is applied by;Tns—>past •••-> (John—past-write+a+letter)^ ' ; . J. ... 1Tq ............... _> (past—John—write+a+letter)
^']['„! ..............._> (John—past—write+a+letter)
_^T^ ...............--> (who—past-write+a+letter)
T̂aux •••••••••••• —> (who—write © past+a+letter)J-T,,b ...............-> (s who ff write ® past S a ft letter S)
m̂orphophonemic rule"--> (who wrote a letter)
Thus (21 ii) can be given.

But in the case of (21 i), the result will be;(Omitting the initial steps.)
Tq ...............-^. (past+John+write-a+letter)
T,,i ..............._> ( a+lefctsr—past + John + write)
T,^ ..•.•.•........-> (what-past+John+write)
(There is no substring Af+v, so that we apply Tdo.)Tdo ...............-> (what-do © past + John + write)
Ultimately 'what did John write' can be generated.
As we defined in III. 1, a kernel sentence is derived from a terminal string by applyingobligatory T rules only. Thus the sentence;
(23) ( i ) John wrote a letteris a kernel sentence, because (23 i) was derived from the terminal string 'John+past
+ write+a+leter' by applying Tnu.x and T,,.b. But the following sentences;
(23) ( ii ) did John write a letter(iii) what did John write(iv) who wrote a letter
are not kernel sentences. Because they are derived by applying not only obligatory
but also optional T rules on the terminal string. The method to decide which sentences
are kernel is an interesting problem. Generally speaking, if we require that the theory
of grammar be as simple as possible, we had better let kernel sentences be simple,
declarative and active sentences. Consequently, all the other sentences may be regarded
as transforms of kernel sentences.
In this section we have only treated Tnoi, Tq and T,,. all of which are based on
obligatory T rules such as Taux, Tivi,, and Tjo. While we have not described T rules
in sufficient detail but we can understand the grammar of English becomes much more
simple and explicit by these rules.
III. 4. Kernel or Non-Kernel Sentences
Up to this point we have been concerned primarily with describing part of the
apparatus of rules in a grammatical theory.
First we provided PS rules for kernel sentences, that is to say, by PS rules we are
given the terminal strminal strings which underlie kernel sentences. Thus we omitted
(be + En) from the PS rule
Ro Auxs—>(have+En) (be+Ing)
If we add (be+En) to R(|, our grammar will be more complicated. If we do so, we
must add special rules indicating that in the case of VinirunaitivB.) it cannot have tlie
auxiliary (be+En), whereas in the case of Vtrane.tivo, it must have (be+En).
Now compare the following two P-markers.

Only by comparing these two P-markers, we are forced to recognize the complexity of
passive sentences. Accordingly, we chose actives as kernel sentences instead of passives.12
Passives can be derived from actives by applying a passive transformation, A passive
transformation is formulated as the following.
Passive-optional
SD : NP - Aux - V - NP
SC : Xi — Xa — X3 — x,i
»X< - X, + be + En Xs — by Xi
By doing this, we can simplify the description of English. To summarize, given, a
terminal strings by PS rules, then we apply obligatory T rules on it and gain a kernel
12 If we chose passives as kernel sentences, there arise many difficulfies. Chomsky explains as thefollowing ; The active transformations would have to apply to strings of the form
(100) NPi-Aux+be+En-V-by+NPaConverting them to NPa—Auz—V—NPi. For example, it would convert
(101) the wine was drunk by the guestsinto "the guests drank the wine',••••••It thus appears that it is the simplest system of phrasestructure for English; the sentence
(102) John was drunk by midnightis also based on an underlying terminal string that can be analyzed in accordance with(lOO)"""But application of the 'active' transformation to (102) does not give a grammatical sentence.

sentence. If we apply proper T rules on this kernel sentence we can generate gram-
matical sentences. Thus all sentences belong to either kernel sentences or transforms.
Accordingly, if we combine PS rules and T rules properly we can gain all the gram-
matical sentences of English and reject ungrammatical sentences.
