Other forms

nagger (noun)


Nag, meaning ‘to annoy by scolding,’ is a relatively new term, and dates back to the early 19th century. Its origin is uncertain, but it is thought to have evolved from a dialectal term, nag, that meant ‘to gnaw,’ and probably came from a Scandinavian source. As such, it can be traced back to the Proto-Germanic gnagan (to gnaw). Nag is related to the Old Norse gnaga (‘to complain,’ but literally ‘to bite or gnaw’) and the dialectal Swedish and Norwegian nagga (to gnaw), as well as the Old Saxon gnagan, the Old Norse and Swedish gnaga, the Middle Dutch and Dutch knagen, the Old High German gnagan and the German nagen (all meaning ‘to gnaw’), and of course the English word gnaw. The noun meaning ‘a person who nags’ dates back to the mid-19th century, and comes from the verb. Nag, meaning ‘a riding pony’ and ‘an old horse,’ dates back to around the year 1400, in the form of the Middle English noun nagge. Its origin is uncertain, but it is thought to be related to the word neigh, of imitative origin.
