Can you exclude the subject from sentence if it is same for both clauses-ex-a cat ran away-comma-and ate all of my lunch?

You're asking about how to combine sentences where the subject is the same in both clauses. Here's how it works, along with some examples:

The Basic Rule:

* Use a comma and a conjunction (and, but, or, for, nor, so, yet) to connect two clauses with the same subject. The subject is only written once.

Examples:

1. Original: The cat ran away. It ate all of my lunch.

Combined: The cat ran away and ate all of my lunch.

2. Original: The dog barked loudly. He chased the squirrel.

Combined: The dog barked loudly and chased the squirrel.

3. Original: The car stopped suddenly. It swerved into the parking lot.

Combined: The car stopped suddenly and swerved into the parking lot.

Important Notes:

* Subject-Verb Agreement: Make sure the verb in each clause agrees with the subject.

* Clarity: If the combined sentence becomes too long or confusing, it's better to keep the sentences separate.
