This listing of 30 common writing errors was compiled by The Pingry School and is used with permission.

A run-on is two independent clauses joined without punctuation. In analytic writing, a semicolon is usually the best solution; a period may make the sentences choppy, and a conjunction adds an extra word. (In dialogue, the period is usually preferred to the semicolon.) A comma splice, where the clauses are joined by a mere comma, is also incorrect.

Exception: Short parallel clauses: We laughed, they wept.

I went to the store it was closed. [Run-on]

I went to the store, it was closed. [Comma splice]

The game is over, however the score is still in dispute.

Whales are warm-blooded, therefore they are not fish.

I went to the store. It was closed.

I went to the store, but it was closed.

I went to the store; it was closed. [Best]

The game is over; however, the score is still in dispute.

Whales are warm-blooded; therefore, they are not fish.
