🔹 What is a complete subject?

The complete subject includes the simple subject (the main noun or pronoun) and all the words that describe or modify it. It tells who or what the sentence is about.

For example:
In *"The big red dog barked,"*
- Simple subject: dog
- Complete subject: The big red dog

Now, let’s go through each sentence:

---

1. My cat ate tuna for dinner yesterday.

- Who did the action? → "My cat"
- "My" is a possessive adjective modifying "cat"
- So, the complete subject is: My cat

✔ Answer: Circle "My cat"

2. The car broke just before they were about to go.

- Who/what broke? → "The car"

4. Jay, who had never lost a game, was disqualified in the match yesterday.

- The main person being talked about is Jay
- "who had never lost a game" is a relative clause that describes Jay — it modifies the subject
- But since it’s part of the subject phrase, it's included in the complete subject
- So, the complete subject is: Jay, who had never lost a game

✔ Answer: Circle "Jay, who had never lost a game"

> Note: This is a compound subject with a descriptive clause. Even though it's long, it all refers to the subject.
