My latest article for The Week looks at the rationale people give for wanting to leave the apostrophe out of Father(’)s Day, Mother(’)s Day, etc.: the fathers, mothers, and others don’t possess the days, so we shouldn’t use the possessive. And so here we see one of the most badly misnamed features in English grammar:
Stop calling possessives ‘possessive’
Sesquiotica 
over and over and over again, you answer things. this is a biggie.
Mother’s Day is about MY mother. Get your generic wishes the hell off my Facebook already. thank you.
