What punctuation is typically used to separate two independent clauses?

To separate two independent clauses, a semicolon is typically used. An independent clause is a complete thought that can stand alone as a sentence. When two independent clauses are closely related in context, using a semicolon effectively links them without the need for a conjunction like "and" or "but."

For example, in the sentence "I wanted to go for a walk; it was raining," the semicolon connects the two complete ideas. Each clause has its own subject and verb but is related to the overall context of the sentence. This usage enhances the flow of writing and maintains the reader's attention on the relationship between the clauses.

Other punctuation marks do not serve this purpose in the same way. A comma is insufficient on its own for separating independent clauses; it can lead to a comma splice if used improperly. A colon signals that what follows will explain or elaborate on what precedes it, which does not apply to two separate but related independent clauses. Similarly, a dash is often used for emphasis or to indicate a sudden change in thought rather than for straightforward separation of two related ideas.
