kaput

English borrowed kaput from German kaputt, meaning 'broken, out of order.' The German word traces back to French capot, a term for being without a single trick in the card game Piquet — that is, losing badly.

What began as a specific gaming term for a total loss in Piquet broadened in German into a general word for anything ruined or done for, and English picked it up with that same broad, everyday sense of 'finished.'

It's a doublet of capot and capote, both of which trace back to the same French root, and it's cognate with Dutch kapot.
