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'.
