The question now arises, how are we to define the subject of a sentence? The question may also be put in a different way: what criteria do we practically apply when we say that a word (or, sometimes, a phrase) is the subject of a sentence? In trying to give a definition of the subject, we shall have to include in it both general points, valid for language in general, and specific points connected with the structure of Modern English. Thus the definition of the subject in Modern English will only partly, not wholly, coincide with its definition, say, in Russian. First let us formulate the structure of the definition itself. It is bound to contain the following items: (1) the meaning of the subject, i. e. its relation to the thought expressed in the sentence, (2) its syntactical relations in the sentence, (3) its morphological realisation: here a list of morphological ways of realising the subject must be given, but it need not be exhaustive, as it is our purpose merely to establish the essential characteristics of every part of the sentence. . . The definition of the subject would, then, be something like this. The subject is one of the two main parts of the sentence. (1) It denotes the thing 1 whose action or characteristic is expressed by the predicate. (2) It is not dependent on any other part of the sentence. (3) It may be expressed by different parts of speech, the most frequent ones being: a noun in the common case, a personal pronoun in, the nominative case, a demonstrative pronoun occasionally, a substantivised adjective, a numeral, an infinitive, and a gerund. It may also be expressed by a phrase.2 In discussing problems of the subject, we must mention the argument that has been going on for some time about sentences of the following type: It gave Hermione a sudden convulsive sensation of pleasure, to see these rich colours under the candlelight. (LAWRENCE) Two views have been put forward concerning such sentences. One is, that the pronoun it at the beginning of the sentence is the formal subject, and the real subject is the infinitive (in this particular case, to see). The other view is, that it is the subject of the sentence, and the infinitive an apposition to it. There is something to be said on both sides of the question. On the whole, however, the second view seems preferable, as the division of subjects into formal and real ones seems hard to justify in general syntactical theory. As we have seen, the definition of the subject given here includes mention of the predicate. This is in accordance with the view stated above, that the two notions are correlative, that is to say, there is a subject in two-member sentences only. In a similar way, a definition of the predicate will have to include mention of the subject. Following the same pattern in the definition of the predicate, we arrive at the following result. The predicate is. one of the two main parts of the sentence. (1) It denotes the action or property of the thing expressed by the subject. (2) It is not dependent on any other part of the sentence. (3) Ways of expressing the predicate are varied and their structure will better be considered under the heading of types of predicate. Here it will suffice to say that among them are: a finite verb form, and a variety of phrases, for instance, phrases of the following patterns: "finite verb + infinitive", "link verb + noun", "link verb + adjective", "link verb + preposition + noun", etc. The assertion that the predicate is not dependent on any other part of the sentence, including the subject, requires some comment. It is sometimes claimed that the predicate agrees in number with the subject: when the subject is in the singular, the predicate is bound to be in the singular, and when the subject is in the plural, the predicate is bound to be in the plural as well. However, this statement is very doubtful. As we have seen above (p. 182), there is much to be said in favour of the view that the category of number in the predicate verb is independent of the number in the subject. This is especially confirmed by sentences like My family are early risers, where the plural number in the link verb shows the plurality of the acting persons, though the subject noun is in the singular. Besides it should be noted that this question of concord or no concord is one that belongs to the level of phrases, not to that of the sentence and its parts. Thus, there seems to be no valid reason for thinking that the predicate is in any way dependent on the subject.
