"Spelt", in my dialect, is incorrectly spelled, and is a noun referring to a variety of wheat.

Now, was the "correction" I just offered you effective and useful, or was it merely irrelevant, provincial, chauvinistic, uninvited, uninviting, and just plain rude?

(A note to downthread grammar trolls: I just used an Oxford comma, boldly, without apology. Have fun.)
