ANSWERED What is your opinion of the rule? Do you follow the rule or do you ignore it? Under what circumstances would you vary from your usual habit of following it or ignoring it?

Your answer should include justification for your opinion about following the rule or ignoring it.

Ending a sentence with a preposition is acceptable because the rule imposes undo restrictions on the English language. Sentences sound more like natural speech when constructed this way. There are times when moving the preposition forward would sound awkward, as Churchill's sentence shows.

Here are several examples of when you would follow the rule:

You are writing in a formal setting and moving the preposition earlier in the sentence doesn't sound awkward or pretentious. Example: "With whom did the king form an alliance?" would be a reasonable substitute for "Whom did the king form an alliance with?"
Sentences that sound bad or are colloquial with the preposition at the end. "Where's your house at?" The word at is not needed in this case. "What did you go and do that for?” The sentence would sound fine if you wrote, “Why did you do that?”
