Hmmm, not by everyone, SRS, especially on this side of the pond.
What is more annoying is when there are words that are spelled differently according to the context, and people use the wrong spelling:
There, their and they’re
Here and hear
Compliment and complement
To, two and too
And also when spellcheck wants you to use American spelling when you’re not American!
accommodation v accomodation
recognise v recognize
colour v color
favourite v favorite
And I could go on, but it might be unnecessary….another hard one!
