Understanding the difference between a simple predicate and a complete predicate is essential for mastering English grammar. Teachers often emphasize this distinction because it helps students analyze sentence structure more effectively. Here are the top 10 things you need to know about simple and complete predicates.
Table of Contents
1. What Is a Predicate?
A predicate tells us what the subject does or is. It always contains a verb. Without a predicate, a sentence cannot express a complete thought.
2. Definition of a Simple Predicate
The simple predicate is the main verb or verb phrase in a sentence. Example: The dog barked. → Simple predicate = barked
3. Definition of a Complete Predicate
The complete predicate includes the verb plus all words that modify or complete its meaning (objects, complements, adverbs, prepositional phrases). Example: The dog barked loudly at the stranger. → Complete predicate = barked loudly at the stranger
4. Key Difference
- Simple predicate = verb only
- Complete predicate = verb + everything attached to it
5. How to Identify a Simple Predicate
Locate the subject first, then find the verb that shows the subject’s action or state. Ignore modifiers and objects.
6. How to Identify a Complete Predicate
Start with the verb, then include all words that describe or complete the action.
7. Examples of Simple vs Complete Predicate
- She dances. → Simple predicate = dances | Complete predicate = dances
- She dances gracefully on stage. → Simple predicate = dances | Complete predicate = dances gracefully on stage
8. Verb Phrases as Simple Predicates
Helping verbs (is, was, will, can, etc.) combine with main verbs to form verb phrases. Example: He will run. → Simple predicate = will run
9. Why This Distinction Matters
- Improves grammar analysis
- Helps students write clearer sentences
- Builds foundation for advanced grammar (compound predicates, passive voice)
10. Teaching Tip
Use worksheets where students underline the simple predicate and circle the complete predicate. This reinforces the difference visually.
