Wherefore and Shakespeare

In early English, a number of new words were formed by combining where with a preposition. In such words, where had the meaning of "what" or "which"—hence, wherein ("in what"), whereon ("on what"), and wherefore ("for what"). Although wherefore as an adverb is rarely used today, the noun form, meaning "an answer or statement giving an explanation," survives in the phrase "the whys and wherefores."
