Missing comma in compound sentence

- Structure first
- Identify clauses and phrases A comma, period or other mark follows the grammatical boundary, not the length of the sentence.
- Meaning
- Choose the relationship Different marks can signal continuation, separation, explanation or interruption.
- Read aloud
- Use sound only as a final check A pause can confirm a boundary, but grammar decides whether punctuation is required.
