A subject is one of the five major elements of clause structure. The other four are: verb, object, complement and adjunct. Subjects are essential in declarative, negative and interrogative clauses.
The subject acts as the ‘doer’ or agent of an action. Subjects are typically noun phrases (e.g. a noun or pronoun and any dependent words before or after it):
