A compound subject is a grammatical subject that consists of two or more nouns, pronouns, or noun phrases joined together, usually by a coordinating conjunction such as "and," "or," or "nor," and acting together as the subject of a sentence or clause. This combined subject shares the same verb and performs the action or is described by the predicate in the sentence. For example, in the sentence "Jack and Jill went up the hill," "Jack and Jill" form a compound subject
. Compound subjects can appear in various sentence structures, including simple, compound, complex, and compound-complex sentences. They help reduce redundancy and make writing more concise by combining multiple subjects into one
. Key points about compound subjects:
- They contain two or more simple subjects joined by conjunctions.
- They control the verb agreement, typically requiring a plural verb when joined by "and."
- They can include modifiers and determiners along with the nouns or pronouns.
- Examples include "Neither Mia nor Ben wanted to go," and "My sister and I are going"
