SUBJECT

SUBJECT A traditional term for a major constituent of the SENTENCE. In a binary analysis derived from logic, the sentence is divided into subject and predicate, as in Alan (subject) has married Nita (predicate). In declarative sentences, the subject typically precedes the verb: Alan (subject) has married (verb) Nita (direct OBJECT). In interrogative sentences, it typically follows the first or only part of the verb: Did (verb) Alan (subject) marry (verb) Nita (direct object)? The subject can generally be elicited in response to a question that puts who or what before the verb: Who has married Nita?—Alan. Where concord is relevant, the subject determines the number and person of the verb: The student is complaining/The students are complaining; I am tired/He is tired. Many languages have special CASE forms for words in the subject, such as the nominative in Latin; and in English the subject requires a particular form (the subjective) in certain pronouns: I (subject) like her, and she (subject) likes me.

Kinds of subject

A distinction is sometimes made between the grammatical subject (as characterized above), the psychological subject, and the logical subject: (1) The psychological subject is the theme or topic of the sentence, what the sentence is about, and the predicate is what is said about the topic. The grammatical and psychological subjects typically coincide, though the identification of the sentence topic is not always clear: Labour and Conservative MPs clashed angrily yesterday over the poll tax. Is the topic of the sentence the MPs or the poll tax? (2) The logical subject refers to the agent of the action; our children is the logical subject in both these sentences, although it is the grammatical subject in only the first: Our children planted the oak sapling; The oak sapling was planted by our children. Many sentences, however, have no agent: Stanley has back trouble; Sheila is a conscientious student; Jenny likes jazz; There's no alternative; It's raining.

Pseudo-subjects

The last sentence also illustrates the absence of a psychological subject, since it is obviously not the topic of the sentence. This so-called ‘prop it’ is a dummy subject, serving merely to fill a structural need in English for a subject in a sentence. In this respect, English contrasts with languages such as Latin, which can omit the subject, as in Veni, vidi, vici (I came, I saw, I conquered: with no need for the Latin pronoun ego, I). Like prop it, ‘existential there’ in There's no alternative is the grammatical subject of the sentence, but introduces neither the topic nor (since there is no action) the agent.

Non-typical subjects

Subjects are typically noun phrases, but they may also be finite and non-finite clauses: ‘That nobody understands me is obvious’; ‘To accuse them of negligence was a serious mistake’; ‘Looking after the garden takes me several hours a week in the summer.’ In such instances, finite and infinitive clauses are commonly postposed and anticipatory it takes their place in subject position: ‘It is obvious that nobody understands me’; ‘It was a serious mistake to accuse them of negligence.’ Occasionally, prepositional phrases and adverbs function as subjects: ‘After lunch is best for me’; ‘Gently does it.’

Subjectless sentences

Subjects are usually omitted in imperatives, as in Come here rather than You come here. They are often absent from non-finite clauses (‘Identifying the rioters may take us some time’) and from verbless clauses (‘New filters will be sent to you when available’), and may be omitted in certain contexts, especially in informal notes (Hope to see you soon) and in coordination (The telescope is 43ft long, weighs almost 11 tonnes, and is more than six years late).
