What to watch:

Learning objectives

Identify the complete and simple subject.
Identify the complete and simple predicate.
Use “who or what?” and “does what or is what?” questions.
Match subjects and verbs correctly.
Repair fragments missing either team.

The two teams

The playful dog runs quickly.

The complete subject is The playful dog. The simple subject is dog. The complete predicate is runs quickly. The simple predicate is runs.

How to find each part

Ask Who or what? to find the subject.
Ask What does the subject do? or What is the subject? to find the predicate.
In questions, a helper may come before the subject.
A complete sentence normally needs both teams.

Try these experiments

Move Part builder from the subject fragment to a complete thought.
Change between one subject and many subjects; watch the verb ending.
Choose an action and tap every predicate word.
Build a question and locate the subject between the helper and action.

Common misconceptions

The subject is not always the first word.
The predicate is more than an action object; it includes the verb and all words that tell about the subject.
Describing words can belong to the complete subject.
A group with only a subject or only a predicate is usually a fragment.
