How to fix a run on sentence: 4 different ways
1. Put period between two independent clauses
2. Put a semicolon between the two independent clauses
3. Add and or but to link the two clauses. This words used to link independent clauses are called coordinating conjunctions and they create a compound sentence.
4. Use a subordinate conjunction (although, after, because, ect.) to introduce one or two clauses. This creates a complex sentence.
