In your own words explain when a comma is necessary to set apart a subordinate clause and when it is not. Provide a sample sentence to illustrate the rule.?

A comma is necessary to set apart a subordinate clause when it precedes the main clause in a sentence. For example, "Although it was raining, we decided to go for a walk." However, if the subordinate clause follows the main clause, a comma is generally not needed, as in "We decided to go for a walk although it was raining." This helps clarify the structure and flow of the sentence.
