means A secretive, ground-dwelling European bird (Crex crex) of grassy meadows, famous for the males' loud, grating, repetitive call given through the night.

from A plain-spoken compound: 'corn' in the old British sense of cereal crops and grassland, plus 'crake' — an imitation of that harsh, rasping cry. 'Crake' is an old word (likely from a Norse root, a cousin of words meaning to croak or caw) that simply echoes the sound the bird makes; the scientific name Crex crex pulls the same trick in Latin. So the name means, roughly, 'the rasper that lives in the hayfields.'
