Some sentences do properly end with a preposition The learnèd fools set you up. Do not give in. This phony rule is nothing we must put up with. Latin sentences may not end with a preposition, but it is perfectly correct in English.
There is nothing grammatically incorrect, at least in the English language, about ending a sentence with a preposition. Technically, this is referred to as "preposition stranding", and it occurs any time a preposition and its object are separated, not just at the end of a sentence (Note, the separation of the preposition and its object must be by more than an adjective or two to qualify as preposition stranding: "with a sunny disposition" is not preposition stranding. Also, preposition stranding usually involves reversing the usual order, i.e., placing the object somewhere before the preoposition.) But wherever in the sentence it occurs, there is absolutely nothing wrong with preposition stranding. What is wrong is to rearrange a sentence in a way that makes it cumbersome or less understandable, all in an effort to follow this false rule.
One example sentence commonly (and deceitfully) used to show that preposition-stranding is incorrect is "Where is the library at?". This sentence is absolutely incorrect, but not because it ends with a preposition. It is incorrect because "at" is not needed. To see this, simply rearrange the sentence by putting "where" after "at", as in "The library is at where?" Doesn't make sense, does it? If you asked the question this way, you would omit "at", and so it is not necessary. However, if I instead asked "Which building is the library in?", that would be perfectly acceptable.
By the way, though the first answerer is correct in his/her conclusion, I need to point out that neither of the first two sentences given as examples actually ends with a preposition. Though "up" and "in" can be used as prepositions, they are not prepositions the way they are used in those two sentences, but are instead adverbs. Also, in the third sentence, though "with" is a preposition, "up" is not. The way you can tell is that a preposition always has an object, somewhere in the sentence, even if it's not immediately after the preposition.
Here are some better examples of grammatically-correct English sentences that end with prepositions:
What are you talking about? ("about" is the preposition, "what" is the object)
That's the girl I'm going out with. ("with" and "that")
What are you looking at? ("at" and "what")
Put this back where you got it from. ("from" and "where (you got it)")
Ending a sentence with a preposition is considered grammatically incorrect in formal writing because it can create ambiguity or awkward phrasing. However, in casual speech and modern writing, ending a sentence with a preposition is generally accepted as long as it does not impact clarity or flow.
It is generally accepted to end a sentence with a preposition in informal spoken English or when the preposition is part of a phrasal verb. In formal writing, however, it is often better to rephrase the sentence to avoid ending with a preposition.
In English, it is generally acceptable to end a sentence with a preposition, especially in spoken language. However, in formal writing, it is often preferred to rephrase the sentence to avoid ending it with a preposition. Adverbs can also appear at the end of a sentence to modify a verb or adjective.
What are you talking about? A preposition is the worst thing in the world to end a sentence with. This is unheard of. This is a habit that you should stay far away from. Rearranging the sentence to remove the preposition from the end of the sentence is the rule that you should abide by.(Hopefully, you have picked up on the sarcasm by this time. Each sentence in the above paragraph ends with a preposition, and all are grammatically correct. There is no rule, at least in the English language, that forbids ending a sentence with a preposition, whether written or spoken, formal or informal.)
It is generally considered acceptable to end a sentence with a preposition in informal settings, but in formal writing, it is recommended to rephrase the sentence to avoid ending with a preposition.
The noun or pronoun at the end of a prepositional phrase is called the object of the preposition. It is the word that the preposition is connecting to other parts of the sentence.
According to proper English grammar, no. "With" is a preposition. You aren't supposed to end a sentence with a preposition.
A preposition is used before a noun or pronoun to show its relationship to another word in the sentence. It indicates location, time, direction, or other relationships between elements in a sentence.

The preposition at is used before an object of the preposition in a sentence. It should not be used at the end of a sentence. Examples: "I was at the store." - Correct (store is the object of the preposition.) "Prepositions should not be used at the end of a sentence." - Correct (end is the object of the preposition that goes with at.) "Where is my phone at?" - Incorrect Instead, one would say, "Where is my phone?"
Yes, in English, it is acceptable to end a sentence with a preposition, despite traditional grammar rules that discourage this practice. It is more important for the sentence to be clear and natural sounding to the reader or listener.
In proper English usage you do not end a sentence in a preposition, so at should not end the sentence Where is Jasmine is sufficient.
Never end a sentence with a preposition.

You can say, "With whom did he leave"
Yes. It is perfectly acceptable.There is a very common misunderstanding that, in proper English grammar, one should never end a sentence with a preposition (of, at, on, in, etc.).It is perfectly acceptable to end a sentence with a preposition, as long as that preposition is critical to the meaning of the sentence.I am Edmond Weiss, author of of the book referred to as Writing Remedies, but which is actually called 100 Writing Remedies. Although this book does contain the passage "Do not end a sentence with a preposition," in fact I never wrote that sentence. What I wrote was: A preposition is a word you should not end a sentence with. The young copy editor at Oryx Press did not get the joke, replaced my sentence with the one you quoted, and refused to follow my instructions to put things back. There is not now, nor has there ever been, any rule against ending an English sentence with a preposition.
The book that I am reading is about ancient civilizations. She was unsure about which path to take. We are going to the park to have a picnic. They are discussing the plan that was proposed. Can you pass me the salt that is on the table?
