nymph: [14] Greek númphē originally meant ‘bride’ (it was related to Latin nūbere ‘take a husband’, source of English connubial and nubile). It subsequently became extended, however, to ‘beautiful young woman’ and ‘female nature spirit, particularly one frequenting water’, and it was in the latter sense that the word first entered English, via Latin nympha and Old French nimphe. The original sense ‘bride’ lies behind nymphomania, coined in the second half of the 18th century. => connubial, nubile
