Wow, what a hard question to answer!
if I had to choose one, I think it would be “defenestrate”. It literally means to throw someone or something out of a window…usually only used in the context of a violent act…
The other, the most useless word in the dictionary is probably “superfluous,” which means “more than is needed, desired, or required.” It’s an unnecessary word that doesn’t add any real meaning to a sentence and can easily be replaced with a simpler term.
What do you think is the most useless word in the dictionary?
