There are a few ways to correct a run-on sentence.
1. Use a period.
This is the most straightforward way to correct a run-on sentence. Simply place a period between the two independent clauses.
Examples:
* Incorrect: The dog ran down the street the car chased it.
* Correct: The dog ran down the street. The car chased it.
* Incorrect: I went to the store I bought some milk.
* Correct: I went to the store. I bought some milk.
2. Use a semi-colon.
A semi-colon can also be used to connect two independent clauses. However, a semi-colon is typically used when the two clauses are closely related in thought.
Examples:
* Correct: The dog ran down the street; the car chased it.
* Correct: I went to the store; I bought some milk.
3. Use a comma and coordinating conjunction.
A comma and coordinating conjunction (and, but, or, nor, so, yet) can be used to connect two independent clauses.
Examples:
* Correct: The dog ran down the street, and the car chased it.
* Correct: I went to the store, but I forgot to buy milk.
4. Rephrase the sentence.
Sometimes, the best way to correct a run-on sentence is to rephrase it. This may involve breaking one of the independent clauses into two shorter clauses.
Examples:
* Incorrect: The dog ran down the street the car chased it.
* Correct: The dog ran down the street when the car chased it.
* Incorrect: I went to the store I bought some milk.
* Correct: I stopped at the store where I bought some milk.
