In its most common usage, "as" functions as a subordinating conjunction. This means it introduces a dependent clause that modifies or explains the main clause. This type of "as" often indicates:

"As" as an Adverb

"As" can also function as an adverb, typically modifying a verb, adjective, or another adverb. It often indicates:
