What purpose do these corrections serve?
These word usage corrections are important because they serve to educate people in the proper use of our own language. If we don't point out these kinds of mistakes, they get perpetuated and the written English language becomes a farce.
It's not a "put-down" or belittling to correct someone on the proper use of a particular word. It's just an educational process.
I admit the English language can be confusing.
Aisle or isle?
Brake or break?
Lose or loose?
Preventive or preventative?
Oriented or orientated?
There, their and they're?
These are just a handful...
As for re-opening the Yellow Hall...no thanks! There is no heat in there! I spent several York meets in that hall during 40-degree outside temps. I'll not do that again.
