nook and cranny, every

Everywhere, as in I've searched for it in every nook and cranny, and I still can't find it. This metaphoric idiom pairs nook, which has meant "an out-of-the-way corner" since the mid-1300s, with cranny, which has meant "a crack or crevice" since about 1440. Neither noun is heard much other than in this idiom.
