Affect and effect. I mean we usually use affect as a verb and effect as a noun but I sometimes see people use effect as a verb as well and I dont know why??

I used to misspell tomorrow often.
Also I wrote propably instead of probably for many years

I used to mispelled prestigious as pretigious for so long too

And back when I was in highschool, my teacher literally corrected me when I used 'skeptical', he said it's sceptical He was a mess of a teacher.

the word embarrassing. i need to check the spelling every time i write it

I notice a lot of people struggle with it's vs. its/then vs. than/affect vs effect/your vs you're/their vs they're/worse vs worst and mistaking should have/should've for should of. And I'm talking about native English speakers/writers, not ESL.

in/on

I used to struggle to spell business

This one tbh

Tons.

appropiration and entepeneur

Pretty much only prepositions UGH. There are so many instances in which I misuse in, on, and at (probably others as well.)

Yaaaas and Yes. I don't think the first is a word.

Necessary and banana. I always sing the Hollaback Girl song when I'm spelling it.

Recently it's been "repetition". Today I think I wrote it as "repition"

Necessary and vacuum

Using in/on in place of the other

is/are

Which/wich

beginning bananana

in/on like a LOT
