For Paty In my language, cog rattle, noisemaker, ratchet: Signal to noise Arabic: from مَطْرَق‎ maṭraq stick, hammer, chatterbox to knock, bang, strike. Aramaic: from טרק‎ to hit, sting, bite, close a door, mix. Talmud: pakia? What is a madra? Rav Papa says: An Arabian whip whose end is split. Suena la matraca noisy, fun, old. Every sound comes from somewhere else. What fortunes will the racket bring?
