Subject
The subject is a noun or noun phrase, pronoun or subordinate clause.
- The dog was sick. Fred felt funny. (noun)
- Mad dogs and Englishmen go out in the midday sun. (noun phrase)
- I am happy. They are jealous. (pronoun.)
- What she said is untrue. (subordinate clause)
* In this kind of analysis a series of noun phrases is a single clause element.
* Pronouns used as subject are in the subject case (I, she, they not me, her, them)
* The subject controls singular-plural verb agreement (You go : she goes) and agreement of reflexive pronoun objects (I injured myself they amused themselves)
* A subject is usually present in a clause, but it may be omitted in non-standard (especially spoken) structures (Drinks like a fish. Gets here when?) or imperatives (Listen to this).
