thrush: Thrush the bird [OE] and thrush the disease [17] are presumably different words, although the origins of the latter are obscure. The bird-name goes back to a prehistoric Germanic *thruskjōn, and has relatives in Latin turdus ‘thrush’ (source of English sturdy), German drossel ‘thrush’, and the now archaic English throstle ‘thrush’. The first record we have of thrush the disease is in Samuel Pepys’s diary, for 17 June 1665: ‘He hath a fever, a thrush, and a hickup’. It may have been of Scandinavian origin (Danish has troske for a similar disease).
