Slide 2 — Run-On Sentences

Slide 3 — Definition

A run-on sentence is a series of independent clauses that are put together in one sentence with no punctuation, often using more than one conjunction. Conjunctions are words like and, but, and or.

Slide 4 — Example

Example of a run-on sentence:

None of my friends liked the movie I did not see it.

There are 2 independent clauses in the sentence. We say that they are “run-on” because the 2 clauses are not separated by any punctuation.

We can fix the sentence by adding the appropriate punctuation and a conjunction.

None of my friends liked the movie, so I did not see it.

We will look at some different options for punctuation in Punctuating Sentences.
