What is a sentence called that contains two or more predicates usually joined by 'and' or 'or'?

A sentence that contains two or more predicates typically joined by 'and' or 'or' is referred to as a compound predicate. This structure allows a single subject to perform multiple actions or to be described in multiple ways, creating a more elaborate sentence without the need for repeated subjects.

For example, in the sentence "The dog barked and wagged its tail," 'barked' and 'wagged' are two predicates that share the same subject, 'the dog.' The use of 'and' effectively combines the actions that the subject is performing, illustrating the concept of a compound predicate. Understanding this structure helps in recognizing how sentences can be constructed to convey more complex ideas efficiently.
