laughingthrush (English)

Where does "laughingthrush" come from?

The English noun 'laughingthrush' is a compound word formed from 'laughing' and 'thrush'[1]. The first element derives via Middle English 'lawghynge'[2] and 'laughen'[4] from Old English forms rooted in the Proto-Germanic 'hlahjaną', which traces back to the Proto-Indo-European onomatopoeic root '*klek-' meaning 'to laugh, cackle'[7][9]. The second element comes from Middle English 'thrusche' and Old English 'þrysċe'[3], stemming from Proto-West Germanic '*þruskijā' and ultimately tracing back to the Proto-Indo-European '*trosdos' meaning 'thrush (bird)'[3][5][13].
