as: [12] Ultimately, as is the same word as also. Old English alswā ‘in just this way’ was used in some contexts in which modern English would use as, and as it was weakly stressed in such contexts it gradually dwindled to als or ase and finally to as. => also
as (adv.)
c. 1200, worn-down form of Old English alswa "quite so" (see also), fully established by c. 1400. Equivalent to so; any distinction in use is purely idiomatic. Related to German als "as, than," from Middle High German also. Phrase as well "just as much" is recorded from late 15c.; the phrase also can imply "as well as not," "as well as anything else." Interjection of incredulity as if! (i.e. "as if that really could happen") is attested from 1995, an exact duplication of Latin quasi.
