* Two Subjects: The sentence has two separate nouns or pronouns that perform the action of the verb.
* One Verb: The action is performed by both subjects together.
Example:
* "John and Mary went to the store."
* Subjects: John and Mary
* Verb: went
Key points about compound subjects:
* Conjunction: The two subjects are often connected by a conjunction like "and," "or," or "nor."
* Agreement: The verb agrees with the compound subject in number. If the subjects are plural, the verb is plural. If the subjects are singular, the verb is singular.
* Meaning: The sentence implies that both subjects are doing the action together.
Example:
* "The dog and the cat ran away." (Both subjects are plural, so the verb "ran" is also plural.)
Important Note: Don't confuse compound subjects with sentences with a single subject and a verb that acts on multiple objects. For example, "John bought apples and oranges" has one subject (John) and one verb (bought), but the verb acts on two objects (apples and oranges).
