Origin of where

before 900; Middle English quher, wher, Old English hwǣr; cognate with Dutch waar, Old High German hwār; akin to Old Norse hvar, Gothic hwar
Can be confusedwe're were wherewhere wherefore (see usage note at the current entry)

Usage note

Whereat ( Where was he at? ) and whereto ( Where is this leading to? ) are often criticized as redundant because neither at nor to adds anything to the meaning of where, and sentences like the preceding ones are perfectly clear and standard without the final at or to. This criticism does not apply to wherefrom, which is fully standard: Where does the money come from? The constructions whereat and whereto occur in the speech of educated people but are rare in formal speech and edited writing.

Word Origin and History for where it's at

at

prep.

Old English æt, from Proto-Germanic *at (cf. Old Norse, Gothic at, Old Frisian et, Old High German az), from PIE *ad- "to, near, at" (cf. Latin ad "to, toward" Sanskrit adhi "near;" see ad-).

Lost in German and Dutch, which use their equivalent of to; in Scandinavian, however, to has been lost and at fills its place. In choosing between at church, in church, etc. at is properly distinguished from in or on by involving some practical connection; a worshipper is at church; a tourist is in the church.

The colloquial use of at after where ("where it's at") is attested from 1859. At last is recorded from late 13c.; adverbial phrase at least was in use by 1775. At in Middle English was used freely with prepositions (e.g. at after, which is in Shakespeare), but this has faded with the exception of at about, which was used in modern times by Trollope, Virginia Woolfe, D.H. Lawrence, and Evelyn Waugh, but nonetheless is regarded as a sign of incompetent writing by my copy editor bosses.

where

adv.

Old English hwær, hwar, from Proto-Germanic *khwar (cf. Old Saxon hwar, Old Norse hvar, Old Frisian hwer, Middle Dutch waer, Old High German hwar, German wo, Gothic hvar "where"), from PIE interrogative base *qwo- (see who).
