トランプ (とらんぷ/TRUMP) noun. Playing cards.
I don’t know how this katakana word got so mixed up. I guess it must have happened over a generation ago. Pre-Donald Trump there was indeed a card game called Trump. My grandmother used to play it with her retired friends along with such other classics as Gin and Pinochle. In Japan, nobody knows the rules of the original Trump. Nobody plays it. Trump just is the word for playing cards. Playing cards are trump.
