Buttons. I don’t say but-ins, I pronounce it like but-tons. Idk why I didn’t do the lazy American thing with that word but I didn’t.

I used to pronounce "adjacent" as adjuhsent.

Tet-nus

Not me, but a friend of mine pronounces rhinoceros as if it rhymes with dinosaur-us.

Most of them. I have that good ol autism speech pattern

"Horror" and "Water."

("Hor-er" and "woo-tur")

I say the word pecan differently depending on what I'm talking about. If it's just the pecan itself I say it like pea-con. If it's a pecan pie I say it pea-can. Not sure why. I also live in a place with a bunch of pecan orchards so the word comes up fairly frequently.

I pronounce milk like melk. Is it wrong, definitely but I’m not gonna change it at this point

I have two:

I pronounce the d in Wednesday. Like wedns-day.

Vagaries - vag-air-ees. I think this is an Irish thing.

Yes but I do this on purpose. Mazda with a flat A like in Aztec. Bag is bayg, measure is maysure. My long Os are longer like Psy saying ope in Gangnam style or like the movie Fargo. Snow is Snew with an Irish accent like Ygritte. There are too many more to recount, about every fourth sentence on average I pronounce a word wrong on purpose, it has become my dialect.
