First of all, do you know what an adverb is?

An adverb clause is a group of words that functions as an adverb in a sentence. It provides information about the verb, adjective, or adverb in the main clause and helps to answer questions such as "when," "where," "why," "how," or "to what extent".

An adverb clause typically begins with a subordinating conjunction like "after," "although," "because," "since," "until," "when," "where," "while," or "if." Here are a few examples:

- After she finished her homework, she went to the park. (The adverb clause "After she finished her homework" tells us when she went to the park.)
- Although he was tired, he continued working. (The adverb clause "Although he was tired" tells us the contrast between his tiredness and his perseverance.)
- Because it was raining, they stayed indoors. (The adverb clause "Because it was raining" provides the reason for their decision to stay indoors.)

To identify an adverb clause, you can:
1. Look for a group of words that starts with a subordinating conjunction.
2. Check if the group of words modifies a verb, adjective, or adverb in the main clause.
3. Determine what kind of information the clause provides (when, where, why, how, to what extent).

Remember, adverb clauses play a crucial role in adding more detail, clarity, and context to a sentence.
