Common Run-On Errors and Solutions
| Error Type | Description | How to Fix It |
|---|---|---|
| Fused Sentence | Two independent clauses joined with absolutely no punctuation. | Add a period, semicolon, or a comma with a coordinating conjunction. |
| Comma Splice | Two independent clauses separated only by a comma. | Replace the comma with a semicolon or add a conjunction like 'and' or 'but'. |
| Polysyndeton (Over-coordination) | Stringing multiple clauses together with too many "and"s or "so"s. | Break the massive sentence into two or three smaller, concise sentences. |
