We have learned that sentences are made up of subjects, or who the sentence is about, and predicates, or what the subject is doing.

If the sentence is missing a subject or predicate, it is not a complete sentence.

Example: peels an orange

If the sentence above only says peels an orange, I don’t know who peels the orange.

• This is the predicate, or the action part of the sentence.
• The sentence is missing a subject, so it is not a complete sentence.
