The Subject Element of a Clause
In statements, the subject element usually appears before the verb:
Snow fell hard.
And after the first verb in questions:
Is she really going to wear that?
In third person present tense, the subject controls whether the verb is singular or plural:
He sees you. They see you.
The subject also controls how certain objects and complements are formed:
I slapped myself. He slapped himself. They slapped themselves.
Amy's my friend. Amy and Holly are my friends.
What Can be a Subject?
Noun phrases, including single nouns:
James ran fast. The bus was on time. Steak, ale, and cake are available.
I like pumas. That interests me. Who owns this?
Some subordinate clauses:
What she did was out of order. Where you live doesn't count.
When you string a list of nouns together, they form one subject in the clause, rather than separating them out. For example:
Amy, Alina, and John were laughing.
(S) (V) (C)
This isn't S + S + S + V + C, but rather S + V + C
