Tatu m

^ Philip Motley Palmer, Neuweltwörter im Deutschen (1939), page 25: Armadill Das Gürteltier; vom gleichbed. span. armadillo entlehnt. Das einheimische Wort Tatu (Tupi tatu — dasypus, Martius) ist für das 16. und 17. Jh. häufig belegt (schon bei Staden 1557 S. 145), wurde aber durch Armadill und später [...] durch Gürteltier zurückgedrängt.

From tatu (“number three”).
