Compound of jack + daw. The first element, also present in Low German Kajak, (North Saxon) Jöker (“jackdaw”), may refer either to its characteristic call, often represented as tchak-tchak, or to the name Jack. The second element means "jackdaw" in itself, from Old English dāƿe, from Proto-Germanic *dēhǭ, from Proto-Indo-European *dʰēk- (“a daw, starling, thrush, similar birds”). Cognate with Old Prussian doacke (“starling”), Latin faccilāre (“the sound or timbre of the thrush”), and German Dohle (“jackdaw”).
