sleepwear

the word 'sleepwear' is a modern english compound noun, transparently formed from two native germanic elements. the first element, 'sleep', maintains its core meaning of a natural state of rest. the second element, 'wear', evolved from the old english verb for 'to carry or have on the body' into a noun denoting articles of clothing, as seen in other compounds like 'footwear' and 'sportswear'. the compound logically and directly describes its function: garments intended for wearing while sleeping. this pattern of creating new words by combining existing, familiar elements is a hallmark of the germanic layer of english vocabulary.

Structure: sleep (to rest in a state of sleep) + wear (garments, things to wear) 'sleep' is from old english 'slæp' (sleep, rest), of germanic origin. 'wear' is from old english 'werian' (to clothe, put on), also of germanic origin, used here in its noun form meaning 'clothing'.
