nook (n.)

c. 1300, noke, "angle formed by the meeting of two lines; a corner of a room," a word of unknown origin. Possibly from Old Norse and connected with Norwegian dialectal nokke "hook, bent figure," or from Old English hnecca "neck," but the sense evolution would be difficult. OED considers the similar Celtic words to be borrowings from English. Meaning "remote or secluded place" is by late 14c.
