How do i manage the language dictionary

I have never and will never ever refer anything as “bud” or “buddy” and every time i type “bud” it gets corrected to bud i am so frustrated with this. I have tried the “shortcut” thing and i can’t count the amount of times it doesn’t help. There should be a way to edit autocorrect’s dictionary… and no i can’t turn off autocorrect i have chubby fingers and i still need help correcting the other mistakes
