When is it okay to end a sentence in a preposition?
I see it a lot, even though my elementary teacher told me it is wrong. This is probably a new development, a sign that our language is in decay. Soon none of us will be able to understand each other. But this sloppiness is a disaster, up with which I will not put.
What are your own experiences with this terrible phenomenon? How may we roll it back? Should moderators strike out at such language abuse? What do you do to correct your friends, family, and colleagues? Do you leave them notes, too? Voice mails? Should all existing literature be corrected and republished as well, the old editions burned?
