All that is said about the subject in a sentence is called the Predicate. A Predicate can be a word or a group of words.
- The children had a hearty laugh.
- The headmaster did not sign my application.
- Where is your new bicycle?
- The flood killed thousands in New York.
- All the roses have wilted due to heat.
The predicate essentially contains a main verb of action, state, possession, or quality. In the above examples, had, sign, be, is, killed, and wilted are the main verbs for their respective sentences.
