Etymology

Origin of dollar

First recorded in 1545–55; earlier daler, from Low German, Dutch daler; cognate with German Taler, short for Joachimsthaler, a silver coin minted in Joachimsthal ( Czech Jáchymov ) in Bohemia

Explanation

Kaching! A dollar is a unit of currency or money. The United States, Canada, and Australia all use the dollar. The symbol for a dollar is $. If you say someone worships the all mighty dollar, that means they’re greedy. A dollar bill is the equivalent of 100 cents. There are also coins with the value of a dollar, although these are used less often in the US than in other countries. Sometimes dollar is shorthand for money, like when the Wu-Tang Clan raps, “Cash rules everything around me, dollar dollar bill y’all.” The word dollar comes from the German thaler, an early unit of German currency.
