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.
I have mostly overcome my prescriptivism, however, two that get me are: liberry (instead of library), and my biggest one is unnecessary apostrophe’s. They are everywhere.
How dare
Apostrophes annoy me, but for whatever reason autocorrect preferences them over the plural form and I hate typing on my phone, so sometimes I just give up
