Comma before conjunction in a compound sentence

Definition

The comma before a conjunction in a compound sentence is used to separate two independent clauses that are connected by coordinating conjunctions like 'and', 'but', 'or', 'nor', 'for', 'so', and 'yet'. This punctuation helps clarify the relationship between the clauses and ensures that each clause can stand alone as a complete thought. Using the comma correctly maintains the flow of the sentence and enhances readability.
