Fun Fact
The origin of “kibosh” is somewhat mysterious and hotly debated among etymologists. One theory suggests it comes from the Irish phrase “cie bais,” meaning “cap of death” (referring to a judge’s black cap worn when pronouncing a death sentence). Another theory links it to the Yiddish word “kabas,” meaning “to suppress.” Yet another suggests it might come from the word “kurbash,” a type of whip used for punishment in some Middle Eastern countries. Despite its unclear origins, “kibosh” entered English slang in the early 19th century and has been putting a stop to things ever since.
(verb) To waver indecisively between different options or opinions; to go back and forth without reaching a conclusion.

Vacillate derives from the Latin vacillare, meaning “to sway” or “to totter” — originally describing the physical motion of something rocking unsteadily from side to side. It entered English in the 16th century carrying both its literal sense of physical swaying and its figurative sense of a mind that cannot settle — rocking back and forth between positions without ever finding its footing on either side.
