Simple Complete Compound Subjects and Predicates

Simple, Complete, and Compound Subjects and Predicates 1. The Subject and the Predicate (Foundation) Every sentence has two main parts: Subject : tells who or what the sentence is about Predicate : tells what the subject is or does Example: “The puppy ran across the field.” Subject = The puppy Predicate = ran across the field The subject answers: Who or what? The predicate answers: What is happening? Simple and Complete Subjects 2. Simple Subject The simple subject is the main noun or pronoun that performs the action. It does not include describing words or phrases. Example: “The curious boy from the dome explored the hills.” Simple Subject = boy Even though the sentence gives more details, the main doer is “boy.” 3. Complete Subject The complete subject includes the simple subject plus all the words that describe or modify it. Example: “The curious boy from the dome explored the hills.” Complete Subject = The curious boy from the dome Simple Subject = boy The complete subject shows the full description of who or what the sentence is about. Simple and Complete Predicates 4. Simple Predicate The simple predicate is the main verb or verb phrase that shows the action or state of being. Example: “The puppy barked loudly.” Simple Predicate = barked 5. Complete Predicate The complete predicate includes: The verb All the words that tell what the subject does or is Objects, modifiers, and complements Example: “The puppy barked loudly at the stranger.” Complete Predicate = barked loudly at the stranger Simple Predicate = barked The complete predicate gives the full action and its details. Compound Subjects and Compound Predicates 6. Compound Subject A compound subject contains two or more subjects that share the same verb. They are usually joined by conjunctions such as and or or. Example: “The scientist and the researcher examined the data.” Compound Subject = The scientist and the researcher Both subjects perform the same action. 7. Compound Predicate A compound predicate occurs when one subject performs two or more actions (verbs). Example: “The dog ran and barked loudly.” Subject = The dog Compound Predicate = ran and barked loudly One subject + multiple actions = compound predicate. Key Distinction Summary Type Description Example Simple Subject Main doer only boy Complete Subject Doer + all modifiers The curious boy from the dome Simple Predicate Main verb only ran Complete Predicate Verb + all details ran across the field Compound Subject Two subjects, one action Brock and Brog walked Compound Predicate One subject, two actions ran and barked loudly Practice Questions 1.

Analysis and Application Sentence: “The cautious researcher from the dome examined the living animal carefully.” Task: Identify the complete subject and the complete predicate. Explain your reasoning. Model Answer: The complete subject is “The cautious researcher from the dome” because it includes the main noun and all the words that describe who is performing the action. The complete predicate is “examined the living animal carefully” because it contains the verb and all the details about what the subject did. Open-Ended Question 2 Sentence: “The small dog ran toward the scientist. The small dog wagged its tail excitedly.” Task: Combine the sentences into one sentence using a compound predicate and explain why the revision is grammatically correct. Model Answer: The small dog ran toward the scientist and wagged its tail excitedly. This revision is grammatically correct because it uses one subject (“The small dog”) and two actions (“ran” and “wagged”), which forms a compound predicate.
