Are there words -- "new words" -- that you use repeatedly over the course of a week or two, then move onto new "new words"?
My current "new words" are disabuse, taciturn and recalcitrant. Tonight at dinner, in attempting to explain to my dinner companion just what it was that I was talking about, I used all three in a sentence:
"I really should try to be less recalcitrant and disabuse myself of the notion of using all three words in a single sentence, thereby rendering myself more taciturn."
At least I think that's what I said.
It might have been something else altogether.
(Previous words include ephemeral, detritus and insiduous.)
