Usage

As a conjunction, one sense of as is “because”: As she was bored, Sue left the room. As also has an equally common use in the sense “while, when”: As the parade passed by, the crowd cheered and applauded. These two senses sometimes result in ambiguity: As the gates were closed, he walked away. (When? Because?) As … as is standard in both positive and negative constructions: The fleet was as widely scattered then as it had been at the start of the conflict. Foreign service is not as attractive as it once was. So … as is sometimes used in negative constructions (… not so attractive as it once was ) and in questions ( “What is so rare as a day in June?” ). The phrase as far as generally introduces a clause: As far as money is concerned, the council has exhausted all its resources. In some informal speech and writing, as far as is treated as a preposition and followed only by an object: As far as money, the council has exhausted all its resources. As to as a compound preposition has long been standard though occasionally criticized as a vague substitute for about, of, on, or concerning: We were undecided as to our destination. As to sometimes occurs at the beginning of a sentence, where it introduces an element that would otherwise have less emphasis: As to his salary, that too will be reviewed. As to what and as to whether are sometimes considered redundant but have long been standard: an argument as to what department was responsible. See also all, farther, like 1, so 1.

Etymology

Origin of as1

First recorded before 1000; Middle English as, als, alse, also, Old English alswā, ealswā “all so, quite so, quite as, as”; cognate with Middle Dutch alse ( Dutch als ), Old High German alsō ( Middle High German álsō, álse, als, German also “so,” als “as, as if, because”); cf. also

Origin of as2

First recorded 1540–50; from Latin as (also assis ); further origin unknown

Explanation

As is an adverb that's usually used to compare one thing to another. You could say, for example, that your cat is as smart as your sister. When you're noting similarities between two things or people, especially when you talk about degree or amount, you'll find yourself using the common adverb as. You might complain that it's as hot as heck, or express disappointment that your homemade casserole doesn't taste as good as when your mom makes it. As comes from the Old English alswā, "similarly."
