In grammar, a compound subject is when a sentence has two or more subjects that are joined by a coordinating conjunction such as “and” or “or.” A compound predicate is when a sentence has two or more predicates that are also joined by a coordinating conjunction.

Here are some examples of compound subjects and predicates:

Compound Subjects: 1. Sarah and Emily went to the park. 2. The dog and the cat are playing in the yard. 3. My mom, dad, and sister are going on vacation.

Compound Predicates: 1. The bird flew and sang in the tree. 2. We ate dinner and watched a movie. 3. She danced and sang on stage.

It is important to note that compound subjects and predicates can also be combined, resulting in sentences with both compound subjects and predicates. For example:

Compound Subject and Predicate: 1. Sarah and Emily went to the park and played on the swings.

These examples demonstrate how compound subjects and predicates can add variety and complexity to sentences.
