The
theory of phrase or word combination in linguistics has a long
tradition going back to the 18-th century. According to Russian
scholars the term ‘word combination’ (словосочетание)
can be applied only to such groups of words which contain at least
two notional words forming a grammatical unit. Thus Soviet linguists
restrict the use of the term ‘word combination’ to combination of
notional words. Western scholars hold a different view of the
problem. They consider that every combination of two or more words
constitutes a unit which they term ‘phrase’. In other words,
western linguists do not limit the term ‘phrase’ to combination
of notional words and do not draw a sharp distinction between the two
types of word-groups such as ‘wise men’ and ‘to the
lighthouse’. The first and the most important difference of opinion
on the question between soviet and western scholarsconcerns the
constituents of the word groups forming grammatical units.
Another
debatable problem in soviet linguistics was whether a predicative
combination of words forms a word combination.
It
is generally known that a sentence is based on predication and its
purpose in communication. A word combination has no such aim. Word
combinations are more like words because they are employed for naming
things, actions, qualities and so on. In contrast with soviet
linguists some western scholars make no difference between subject –
predicate combinations of words and other word combinations, though
some western theories bear considerable resemblance to Russian ideas.
There’s
no traditional terminology in the works of English and American
scholars discussing combinations of words; and different terms are
used to express the same idea (phrase, combination of words, cluster
of words, word group).
9. The Sentence
When
we speak or write we convey our thougths through sentences. A
sentence is the only unit of language which is capable of expressing
a communication containing some kind of information. But linguistics
is at difficulty to define it. One of the definitions is ‘the
sentence is the smallest communication unit expressing a more or less
complete thought and having a definite grammatical structure and
intonation’. In most sentences intonation functions as part of a
whole system of formal characteristics.
The sentence and the word group (phrase)
Neither
words no word groups can express communication. Cf. the arrival of
the delegation is expected next week (a sentence). It is a structure
in which words are grouped (arranged) according to definite rules
(patterns).
Another
difference between the sentence and the phrase is predicativity.
Predicativity comprises tense and mood components. The sentence
together with predicativity expresses a fact, while a phrase gives a
nomination without time reference:
The
doctor arrived. The doctor’s arrival.
Predication
is a word or combination of words expressing predicativity. Thus the
essential property of sentence is predicativity and intonation.
Classification of Sentences
Sentences
are classified 1) according to the types of communication and 2)
according to their structure.
In
accordance with the types of communication sentences are divided
into:
Declarative
(giving information). E.g. the book is interesting (statement).
Interrogative
(asking for information). E.g. is the book interesting? (question).
Imperative
(asking for action). E.g. give me the book! (command, request).
Each
of these 3 kinds of sentences may be in the affirmative and negative
form, exclamatory and non- exclamatory.
Types of
Sentences According to Structure
I
a) Simple sentences containing one predication (subject-predicate
relationship)
b)
Composite sentences containing one or more predications Composite
sentences are divided into compound and complex sentences.
II.
Simple sentences and main clauses may be two-member and one-member
sentences.
The
two-member sentence pattern is typical of the vast majority of
sentences in English. It is a sentence with full predication. (The
Sun shines. She walks fast).
If
a simple sentence contains the subject and the predicate only, it is
called unextended. E.g. spring came.
If
a sentence comprises secondary parts besides the main parts, it is
called extended. E.g. Dick came home late.
The
one-member sentence contains only one principle part, which is
neither the subject nor the predicate. E.g. Thieves! Fire! A cup of
tea, please! A one-member sentence sometimes resembles a two-member
sentence. E.g. No birds singing in the dawn. It may be complex in
structure: e.g. And what if he had seen them embracing in the
moonlight?
Imperative
sentences with no subject also belong here: Get away from me!
If
the main part is expressed by an infinitive, such a one-member
sentence is called an infinitive sentence: Oh, to be in England!
The
exclamatory character is a necessary feature of these sentences.
Infinitive sentences are very common in represented speech.
Types of
One-member Sentences in English
Nominative
(substantive) E.g. Another day of fog.
Verbal
(Imperative: Don’t believe him! ,Infinitive: Only to think of it!
,Gerundial: No playing with fire!)
Adjectival
one-member sentences: Splendid! How romantic!
Types of
Sentences According to their Completeness
-
Complete
(non-elliptical) sentences. -
Incomplete
(elliptical) sentences.
Elliptical
sentences are such sentences in which one or several parts are
missing as compared with analogous sentences where there is no
ellipsis. Elliptical sentences may freely be changed into complete
sentences, the missing part of the sentence being supplied from the
preceding or following context, by means of intonation: e.g. I sat
near the window, he – near the door (= he sat near the door).
Playing, children? (= are you playing, children?) Cf. A small but
cosy room (a one-member sentence); in the background stands/ is a
little writing table (an elliptical two-member sentence). The main
sphere of elliptical sentences is of course dialogue.
