As an editor, I see spelling mistakes everywhere. I thought I’d compile a list of the correct version of 20 common spelling mistakes in English that I often notice while out on the town or peering at a screen. Hopefully, this list can serve as a reminder to folks about how to be correct in spelling some of the trickier words in the English language.

Advise – Verb. Ends with a “z” sound. My doctor advised me to eat an apple a day.
A lot – Two words, never one. The garden has a lot of flowers.
Breath – Noun. Rhymes with “Seth.” Take a deep breath.
Breathe – Verb. Rhymes with “seethe.” Relax and breathe.
