Prepositions Are Not to End Sentences With

"That is the kind of arrant pedantry up with which I will not put."

- Attributed to Winston Churchill on being criticized for this

A preposition, a specific type of adposition, is a word describing a relationship between two nouns. These include words such as "on", "to", "beneath", "before", etc.

As noted in the link, the word is a lot more complex than it seems, and not every use of the words that seem like a preposition, actually is a preposition. But the most well known thing about them is that you supposedly cannot end sentences with them (also known as stranding a preposition).

This is actually applying Latin grammar rules to English, and while some of those can actually apply in the latter language (like no double negatives), this one doesn't (same with splitting infinitives. Many sentences just don't flow in English if this rule is shoehorned in (which means ending on a preposition is bad when it breaks the flow, not this "rule").

In fiction, there are different reactions to this. Who states the rule might be accused of being a Grammar Nazi. Or those called on for doing this might reply in a snarky manner. Or those called on might instead try their best to avoid breaking this rule. Basically it's whichever is funnier.

Can often invoke In Which a Trope Is Described, the title of which is the grammatically correct expression of 'a trope is described in'.

Prepositional Phrase Equals Coolness is a trope to compare with.

"Mountie #1: Oh really. Well, what would you say? Mountie #2: Well, I guess I'd say either, "Go back from where you came", or the preferred Queen's English, "Go back, thee, from whence thou came.""
 * In Beavis and Butthead Do America, Agent Flemming admonishes a fellow ATF agent for doing this. That agent then ties his sentences in knots trying to get around this.
 * This is what sparks the hilarity in Downfall of Grammar.
 * In Canadian Bacon, one of the Mounties tells the heroes to "go back to where you came from." The other Mountie tells him that you can't end your sentence with a preposition, and proceed to debate this while the heroes escape.

"Sam: She's trying to become the kind of waitress that you'd enjoy being waited on by. Diane: (whispering) You just ended that sentence with two prepositions... Sam: Don't you have customers to deal with? Diane: That ended with a preposition, too... Sam: Don't you have customers to deal with, mullet head?"
 * In an episode of Cheers, Diane dreams that Sam's boorishness has just been an act for the bar patrons; he's actually cultured and erudite.

Sam's response: "Diane, do you realize you just ended that proposition...with a preposition?"
 * This is a Running Gag between those two, first used in "The Tortelli Tort". When Ed threatens to sue the bar over Carla assaulting him, Sam tries to convince him that Carla is getting therapy for her anger problems:

"Doug: THAT'S WHAT I GOT A PROBLEM WITH! *hangs up' Frasier: ...I think what he means is, that is a thing with which he has a problem."
 * There's an episode of Frasier where Martin is writing someone a letter and Niles, reading over his shoulder, corrects him for ending a sentence with a preposition. We see Martin, rather annoyed, writing something on the paper and underlining it, gesturing to Niles, to which Niles replies, "Not to be technical, but 'off' is a preposition too."
 * In another episode Frasier corrects a caller who uses the word "literally" in the complete wrong way, bringing said caller to get angry about people who "nit-pick on your grammar when they come to you for help".

Then Leonard asks, "What are you talking about?"
