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
Usage note
Where … at ( Where was he at? ) and where … to ( 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 where … from, which is fully standard: Where does the money come from? The constructions where … at and where … to occur in the speech of educated people but are rare in formal speech and edited writing.
where's
[hwairz, wairz]

See contraction.
