What are some facts about compound predicates?

Compound predicates are defined as two or more main verbs that are attached to one subject in the sentence. When two verbs are joined in this form, it is not proper to place a comma before the "and."

There is one exception to the two verb rule, which is if the first element contains another conjunction, a comma is sometimes added before the joining conjunction. This helps avoid confusion within a sentence. When joining three or more verbs, a comma is used before the conjunction. One example of a simple use of a compound predicate is "The performer belted out the song and danced with enthusiasm."
