8. Definition…
An adverb clause is a subordinate (dependent clause) that modifies a verb, an adjective, or an adverb.
Like an adverb an adverb clause tells where, when, how, why, to what extent or under what condition.

…beginning, middle or end…
EXAMPLES:

(modifies the verb sit and tells where)

(modifies the verb go and tells when)
Sammy and Alexandra look as though they have some exciting news for us.
(modifies the verb look, telling how S. and A. look)

(modifies the adjective Happy, telling why Maia was happy.)
Will can climb higher than I can.
(modifies the adverb higher, telling to what extent or how much higher Will can climb)

(modifies the verb will go, telling under what condition we will go to the beach.)

11. COMMA RULES…
When an adverb clause begins a sentence, it is followed by a comma. ,

12. Subordinating Conjunctions:
An adverb clause is introduced by a subordinating conjunction—a word that shows the relationship between the adverb clause and the word or words that the clause modifies.

13. Common Subordinating Conjunctions:
after as though since when
although because so that whenever
as before than where
as if how though wherever
as long as if unless whether
as soon as in order that until while
