Sentences (specially when people are talking) finished with words like with,to,from (prepositions ). Example:
Whom am I speaking with ? (Not only in questions )
I don't understand how to use and meaning ? Sorry for the bad English
Most sentences that end with prepositions fall into one of three categories:
I saw the building blow up. (blow up is a phrasal verb)
Please remember to turn the lights off. (turn sth off is a phrasal verb)
I don't feel like cooking tonight, so let's eat out. (eat out is a phrasal verb)
Here are the keys I was looking for. (could be: I was looking for these keys.)
Jim is someone I can't get along with. (could be: I can't get along with Jim.)
That is an issue I just don't care about. (could be: I just don't care about that issue.)
Who are you looking for?
What are you looking at?
Where are you from?
Occasionally, you might find a sentence that ends with a preposition because it is poorly worded. This led to a mantra that said, "You shouldn't end a sentence with a preposition." However, there are plenty of occasions where it's perfectly fine to end a sentence with a preposition, so this guidance is often called a "myth" instead of a "rule." For what it's worth, Grammar Girl put "Don't end a sentence with a preposition" at the top of her Top 10 Grammar Myths.
Consider these two examples:
Let me spread the frosting on.
Some might argue that sentence could be improved, either by being more specific:
Let me spread the frosting on the cake.
or by omitting the preposition altogether, because it's unnecessary:
Let me spread the frosting.
Sometimes, though, it's best to leave the preposition alone! For example:
Let me help you take your coat off.
You would not want to say, "Let me help you take your coat." Also, "Let me help you take your coat off your body" would sound awkward, too. A purist would say that it could be reworded:
Let me help you take off your coat.
but "take your coat off" sounds normal and idiomatic, and most people wouldn't consider it bad form.
