Prepositions

I've learned that the Prepositions are words which link nouns, pronouns and phrases to other words in a sentence and also it is usually describe the position of something, the time when something happens and the way in which something is done, although the prepositions "of," "to," and "for" have some separate functions. Prepositions can also be used to end sentences like this "What did you put that there for?" it is a preposition because i've use "for" in the last of this sentence, that is the preposition.
