Etymology

Origin of greenback

An Americanism dating back to 1860–65; green + back 1

Explanation

A greenback is a dollar bill. Grab some greenbacks, I hear the ice cream truck coming down our street! The slang term greenback is a little old-fashioned, but it's a perfectly good way to say "buck" or "dollar." You might ask the barista at your neighborhood cafe, "How many greenbacks do I owe you?" or tell your mom you need to borrow some greenbacks and you'll pay her back next week. The word has been used since U.S. money was first printed using green ink, in 1778.
