Here's a breakdown:
* Adverbial clauses modify verbs, adjectives, or other adverbs, providing information about:
* How: *He ran as fast as he could.*
* When: *She arrived after the party started.*
* Where: *We went to the beach.*
* To what extent: *He was so tired that he fell asleep.*
Key features of adverbial clauses:
* They are usually introduced by subordinating conjunctions (e.g., because, although, since, while, when, where, if, unless, etc.).
* They contain a subject and a verb.
* They provide additional information about the main clause.
Examples:
* How: *He painted the picture with great care.*
* When: *We went to the store before it closed.*
* Where: *The dog hid under the bed.*
* To what extent: *He was so excited that he couldn't sleep.*
