When is a dependent clause usually separated from an independent clause?

A dependent clause is typically separated from an independent clause by a comma when the dependent clause comes before the independent clause in a sentence. This practice helps clarify the relationship between the two clauses and enhances the readability of the sentence. For example, in the sentence "Although it was raining, we went for a walk," the comma indicates a pause after the dependent clause, which provides additional information about the independent clause.

When a dependent clause follows an independent clause, no comma is used. For instance, in the sentence "We went for a walk although it was raining," the lack of a comma indicates that the dependent clause is closely related to the main idea.

This convention ensures that readers can easily identify the main components of the sentence, particularly when the dependent clause is positioned at the beginning. Such punctuation rules enhance clarity and structure in writing.
