Comma or Semicolon Worksheet | Punctuation Activity - Free Printable

Let's solve this "Comma or Semicolon Worksheet: Avoiding Comma Splices" step by step.

---

🔹 Key Rules Recap:

- Semicolon (;) joins two independent clauses (each can stand alone as a sentence).
- Example: *We found footprints; they led behind the garage.*
- Comma (,) joins an independent clause with a dependent clause.
- Example: *Although we found footprints, they didn’t lead anywhere.*

> ✔ Dependent clauses start with subordinating conjunctions like:
> - although, even though, because, since, unless, once, when, now that, etc.
>
> ✔ Independent clauses can stand alone.

🧠 Key Takeaway:

- Use semicolon only between two complete sentences (independent clauses).
- Use comma when joining an independent clause with a dependent clause (which cannot stand alone).

This helps avoid comma splices — a common grammar mistake where two independent clauses are joined only by a comma.
