Origin & History of “frog”

Frog comes from Old English frogga, which probably started life as a playful alternative to the more serious frosc or forsc. this derived from the pre-historic Germanic *fruskaz, which also produced German frosch and Dutch vorsch. Its use as a derogatory synonym for ‘French person’ goes back to the late 18th century, and was presumably inspired by the proverbial French appetite for the animals’ legs (although in fact frog as a general term of abuse can be traced back to the 14th century, and in the 17th century it was used for ‘Dutch person’). It is not clear whether frog ‘horny wedge-shaped pad in a horse’s hoof’ (17th c.) and frog ‘ornamental braiding’ (18th c.) are the same word; the former may have been influenced by French fourchette and Italian forchetta, both literally ‘little fork’.
