Misspelling and getting it right!

So many times I see a root word and add suffixes. Today was especially good for that, but not for the long words, I mess up on the short words.

My brain does this:

MINE - hole in the ground.✅
MINER - someone who mines✅.
(Brain- yep, nailed it).
PINE - to yearn for something ✅.
PINER - someone who pines ❌.
(Brain- really? I’m sure that’s a word).
PIES -plural of pie ✅.
PIER - someone who pies ✅.
(Brain - wait, that’s a word????).
(Windows shut down music).
(Brain - “peer”, not ‘pyre’…. Idiot!).
