fey / fā/ • adj. giving an impression of vague unworldliness: his mother was a strange, fey woman. ∎  having supernatural powers of clairvoyance.

fey originally (in Old English, in form fǣge) fated to die soon; the word is of Germanic origin, and related to German feige ‘cowardly’.

The original meaning is still current in Scottish usage, but from the early 19th century the word has developed a more general sense of giving an impression of vague unworldliness, having supernatural powers of clairvoyance.
