A comma splice is a common grammar mistake that occurs when the writer connects two separate ideas by using a comma. This mistake can be spotted by reading the sentences and realizing that the two clauses are independent. This is the case of the sentence "The sound of the trumpets startles me, I’m on my feet and at the mouth of the cave in a flash". A comma splice can be corrected by separating the sentences using a period, a semicolon or a conjunction.
