Introductory Adverb Clauses
* If the adverb clause comes before the main clause, it's usually followed by a comma. This is true regardless of whether the adverb clause is short or long.
* Example: *Because it was raining, we stayed inside.*
* If the adverb clause comes after the main clause, it does not need a comma.
* Example: *We stayed inside because it was raining.*
Within a Sentence
* Adverb clauses within a sentence generally do not require commas unless they are used to set off a parenthetical element or to avoid ambiguity.
* Example: *The dog barked loudly, although he was usually quiet.*
Key Points
* Adverb clauses are groups of words that modify verbs, adjectives, or adverbs. They often answer questions like "when," "where," "why," or "how."
* The comma after an introductory adverb clause helps to clearly separate the clause from the main clause. This makes the sentence easier to read and understand.
