nightingale: [OE] The nightingale’s name, appropriately enough, means literally ‘nightsinger’. It represents a 13th-century alteration of an earlier nihtgale, which goes back to a prehistoric Germanic compound formed from *nakht ‘night’ and *galan ‘sing’ (a relative of English yell [OE] and possibly of gale). Related Germanic forms include German nachtigall, Dutch nachtegaal, Swedish näktergal, and Danish nattergal.
