A word (one of the parts of speech and a member of a closed word class) that shows the relationship between a noun or pronoun and other words in a sentence.
The combination of a preposition and a noun phrase is called a prepositional phrase. A word group (such as in front of or on top of) that functions like a simple, one-word preposition is called a complex preposition.
Prepositions convey the following relationships: agency (by); comparison (like, as . . . as); direction (to, toward, through); place (at, by, on); possession (of); purpose (for); source (from, out of); and time (at, before, on). See "Observations," below.

Etymology:
From the Greek, "put in front"Examples:
- "We must not confuse dissent with disloyalty."
(Edward R. Murrow) - "Yes, I lied to you. Of course it makes you look fat. I've never been to Brussels. It is pronounced 'egregious.' By the way, no, I've never met Pizzaro, but I love his pies. And all of this pales to utter insignificance in light of the fact that my ship is once again gone."
(Jack Sparrow, Pirates of the Caribbean: At World's End, 2007) - "To this day, I remain impressed by the ability of Britons of all ages and social backgrounds to get genuinely excited by the prospect of a hot beverage."
(Bill Bryson, Notes From a Small Island. Doubleday, 1995) - "[Miss] Piggy is certainly hard, but that's just part of the job. I don't even think about it. She's also hard because I have to reach down into the feminine part of myself and bring that up. It's not just the surface with her. There are a lot of neuroses in her. So I have to come from a different place with Piggy."
(Frank Oz) - Dr. Wilson: Beauty often seduces us on the road to truth.
Dr. House: And triteness kicks us in the nads.
(House M.D.) - Texan: Where are you from?
Yale student: I come from a place where we don't end our sentences with prepositions.
Texan: Okay. Where are you from, jackass?
Observations:
- "It is important to be aware that some words that have the form of a preposition do not have the same function.
The girl read in the library
The form of the preposition in is identical in each case, but the function is different. In the first sentence, in describes where the girl is reading--it is therefore a preposition of place. In the second sentence, however, in is directly related to the verb kicked--in this case, it is called a particle."
The rioters kicked in the door.
(Sara Thorne, Mastering Advanced English Language. Palgrave Macmillan, 2008) - In English, three prepositions, namely of, to and by, play roles closely integrated with case and the grammatical structure of clauses. Thus:
- of is associated with a variety of possessive or (loosely speaking) 'genitive' constructions, as in the book of the teacher, the arrival of the ferry and the mortification of the flesh
- to is a marker of indirect objects or 'dative case,' as in We donated our earnings to the Dog and Cat Home
- by marks the noun phrase is a passive clause corresponding to the subject of the related active clause, as in We were ruined by the currency speculators or Our ruination by the currency speculators.
- "Learners seem to make mistakes with prepositions for various reasons.
"Some of these reasons have to do with English itself: For example, a learner may say by random instead of at random, because by and at are sometimes similar in meaning, and/or because random and chance can be similar in meaning (e.g. a random result ~ a chance result), or because the phrases by chance and at random are similar enough in meaning to induce unintentional cross-association (~ 'cross-swapping') of words. . . .
"More often perhaps, mistakes stem from differences between English and the mother tongue. For instance, Japanese has postpositions not prepositions (and not many of them) while Korean has no such words at all."
(Seth Lindstromberg, English Prepositions Explained, 2nd ed. John Benjamins, 2010) - "The Preposition at the end of a sentence; a common fault with [Ben Jonson], and which I have but lately observ'd in my own writings."
(John Dryden) - "Those who lay down the universal principle that final prepositions are 'inelegant' are unconsciously trying to deprive the English language of a valuable idiomatic resource, which has been used freely by all our greatest writers."
(Henry Fowler, Modern English Usage, 1921)
