A compound predicate occurs when a sentence has two or more verbs or verb phrases that share the same subject. This structure allows the writer to convey multiple actions or states of being without repeating the subject. For example, in the sentence “Sarah ran to the store and bought some milk,” both actions are linked to Sarah. Using a compound predicate can make sentences more concise and engaging. It helps to streamline writing by combining related actions. For instance, “The dog barked and wagged its tail” shows two actions performed by the dog in a single, clear statement.
