A preposition is a small linking word that shows how a noun or pronoun relates to the rest of the sentence — most often its place, direction, time, or manner. Everyday examples include in, on, at, to, from, of, by, with, and under, as in “the cat slept under the bed.” And to settle the oldest myth in English grammar right away: yes, you can end a sentence with a preposition — you always could.
A preposition never works alone. It introduces a noun, pronoun, or noun phrase — its object — and the two together form a prepositional phrase. In “she left the letter on the desk,” the preposition on connects the verb left to the noun desk and tells you where. Change only the preposition and you change the whole meaning: the letter could be on, under, beside, near, or in the desk.
Because the object belongs to the preposition, a pronoun object takes its object form: “a gift for her” (not “for she”) and “between you and me” (not the very common “between you and I”).
English has more than 100 prepositions, but a small group does most of the heavy lifting. Here are the everyday ones, grouped by the relationship they express.
Some prepositions are two or three words long — called complex or phrasal prepositions: according to, because of, instead of, in spite of, next to, out of, due to, ahead of. They act as a single unit: “We stayed indoors because of the rain.”
Most preposition errors aren’t about grammar rules at all — they’re about idiom. English simply pairs particular words with particular prepositions, and the wrong pairing sounds off to a native ear.
Yes — and you always could. The belief that a sentence must never end with a preposition is a myth, not a rule of English. It was formulated in the 17th century by the grammarian Joshua Poole and popularised by the poet John Dryden, who in 1672 criticised Ben Jonson for the habit — largely because Latin does not allow a stranded preposition and Dryden’s era idolised Latin. English is not Latin, and serious usage experts abandoned the “rule” more than a century ago.
Every major authority now agrees. The Chicago Manual of Style has accepted terminal prepositions since 1906 and calls the old caveat “an unnecessary and pedantic restriction.” Merriam-Webster, Fowler’s, and Garner’s say the same. Contorting a sentence to move the preposition often produces stilted English — hence the joke long (and wrongly) attributed to Winston Churchill: “This is the sort of English up with which I will not put.”
In many sentences, ending with a preposition is the only natural option:
The one real caveat is to drop a preposition that adds nothing. That’s about redundancy, not position:
Words such as after, before, since, and until can be either. As a preposition it takes a noun object: “after the meeting.” As a conjunction it introduces a whole clause with its own verb: “after we met.” Same word, different job.
In “turn off the light,” off isn’t really a preposition — it’s a particle that belongs to the phrasal verb turn off. A true preposition needs an object: compare “he ran up the hill” (preposition — up governs hill) with “he gave up” (particle — no object).
Like is a preposition and takes a noun: “he sings like a professional.” As introduces a clause: “do as I say.” In careful writing, prefer “as I said” to “like I said,” though the latter is common in speech.
For the spatial prepositions, picture a mouse and a box: a preposition is anywhere the mouse can go — in, on, under, over, beside, behind, through, past, around, near, or between the box. It’s a quick, reliable test, but remember it only catches place and direction words; abstract prepositions like of, for, and despite don’t fit the picture yet are just as real.
Prepositions are one of the clearest dividing lines between American and British English. Neither version is “wrong” — just match your audience.
Learn the handful of common prepositions and their idiomatic partners, and the rest is confidence: these are the smallest words in English, they map time and space onto almost every sentence you write — and they’re free to sit at the very end whenever that sounds best.
Yes. Ending a sentence with a preposition is completely correct and often the most natural phrasing — as in “Who are you talking to?” The idea that it’s wrong is a 17th-century myth borrowed from Latin, and every major style guide, including Chicago and Merriam-Webster, rejects it. Just avoid redundant ones, like the “at” in “Where are you at?”
The nine most frequent are of, to, in, for, with, on, at, by, and from. Other everyday prepositions include about, into, over, under, between, through, against, during, and without. These small words handle relationships of place, time, direction, and connection, and just a dozen or so account for the vast majority of preposition use in ordinary English.
Prepositions are usually grouped by the relationship they express: prepositions of place (in, on, under), time (at, before, during), and direction or movement (to, into, through). Others show manner, cause, or connection (by, with, of, despite). Most are single words, but some are two or three words long, such as “according to” and “because of.”
No. “The” is an article (a type of determiner), not a preposition. Articles — a, an, and the — introduce and specify nouns, while prepositions show a relationship such as position or time. It’s easy to confuse them because both are short and appear constantly, but they do completely different jobs in a sentence.
A preposition takes a noun or pronoun as its object and shows a relationship: “before lunch.” A conjunction joins two clauses, each with its own verb: “before we ate.” Some words — after, since, until — can be either, and the test is simple: if a full clause follows, it’s a conjunction; if only a noun follows, it’s a preposition.
