[Middle English, from Old English hwȳ; see kwo- in Indo-European roots.] Usage Note: Many critics have held that why is redundant in the expression the reason why, as in The reason why he accepted the nomination is not clear. While it is true that why could be eliminated from such examples with no loss to the sense, the construction has been used by reputable English writers since the Renaissance.
