Ετυμολογία

Attested since the mid-16th century, from early Dutch daler, daalder, from German Taler, Thaler (“dollar”), from Sankt Joachimsthaler, literally “of Joachimstal”, the name for coins minted in German Sankt Joachimsthal (“St. Joachim's Valley”) (now Jáchymov, Czech Republic). Ultimately from Joachim + Tal (“valley”). Possibly reinforced by the Dutch leeuwendaalder, which was also used in the American colonies. Cognate to Danish daler. Doublet of taler.
