One of mine (I have many yay neurodivergece) is when people say the phrase "a broken clock is right twice a day". The phrase is actually "a stopped clock is right twice a day." A clock that is stopped will definitely be right twice a day but a clock that is broken could be right multiple times a day or not at all depending on how it's broken. Maybe it's just a little slow running in which case it'll never be right. Maybe it's spinning wildly out of control so it'll be right a lot but still useless.
It annoys the shit outta me and it is so dumb it definitely should not. Anyway your turn.
It never stops bothering me when people say "comprised of", as opposed to just "comprises", or "composed of".
I try to remind myself that I'm witnessing the evolution of language in real-time, but it just annoys me that what causes language to evolve is just people misusing it.
