In a sentence, what is the role of the predicate?

The predicate serves a critical function in a sentence by providing information about what the subject is doing or what is being asserted about the subject. It generally includes the verb and any accompanying words that elaborate on the action, state, or quality of the subject. For example, in the sentence "The cat sleeps on the couch," the predicate is "sleeps on the couch," which tells us what the cat (the subject) is doing. Understanding the role of the predicate is essential for comprehending sentence structure, as it conveys the main action or description related to the subject, making sentences complete and meaningful.
