Tchotchke
Etymology
From Yiddish "tsatske," which comes from a Slavic source (compare Polish and Russian dialect words for a trinket or plaything). It entered American English carrying a faint affection-tinged disdain: these are charming, useless little things. The word’s tangle of consonants has made it a favorite for its sheer fun to say.
noun · /CHOCH-kuh/
A small decorative trinket or knickknack of little real value.
What it names
The exact word for the cheap little object that clutters shelves — souvenirs, giveaways, desk toys — that you neither use nor quite throw away.
Example
The conference gave out branded tchotchkes — a stress ball, a keychain, a tiny plastic robot.
