preposition Cultural  
  1. A part of speech that indicates the relationship, often spatial, of one word to another. For example, “She paused at the gate”; “This tomato is ripe for picking”; and “They talked the matter over head to head.” Some common prepositions are at, by, for, from, in, into, on, to, and with.


Grammar

The often heard but misleading “rule” that a sentence should not end with a preposition is transferred from Latin, where it is an accurate description of practice. But English grammar is different from Latin grammar, and the rule does not fit English. In speech, the final preposition is normal and idiomatic, especially in questions: What are we waiting for? Where did he come from? You didn't tell me which floor you worked on. In writing, the problem of placing the preposition arises most when a sentence ends with a relative clause in which the relative pronoun ( that; whom; which; whomever; whichever; whomsoever ) is the object of a preposition. In edited writing, especially more formal writing, when a pronoun other than that introduces a final relative clause, the preposition usually precedes its object: He abandoned the project to which he had devoted his whole life. I finally telephoned the representative with whom I had been corresponding. If the pronoun is that, which cannot be preceded by a preposition, or if the pronoun is omitted, then the preposition must occur at the end: The librarian found the books that the child had scribbled in. There is the woman he spoke of.
