Introduction to Prepositions

Overview

A preposition is a small word that connects a noun or pronoun to another part of the sentence. It shows a relationship between two things, such as where something is, when something happens, or how something moves. Without prepositions, sentences would be unclear and incomplete.

English has many prepositions, but a small group of them appears again and again in everyday speech and writing. Words like in, on, at, to, from, and with are among the most common. Learning these first gives beginners a strong foundation for understanding how sentences are built and how ideas are connected.

Prepositions are nearly always followed by a noun, a pronoun, or a noun phrase. This combination of a preposition and the word that follows it is called a prepositional phrase.

What a Preposition Does

A preposition shows the relationship between two parts of a sentence. That relationship can be about place, time, direction, or a number of other connections. The noun or pronoun that follows a preposition is called the object of the preposition.

In each example, the preposition is the link between two pieces of information. Remove it, and the sentence either breaks down or loses an important detail.

Common Prepositions of Place

Prepositions of place tell where something or someone is. The three most important ones at this level are in, on, and at.

In is used for enclosed spaces, areas, and locations where something is contained or surrounded.

On is used for surfaces, and also for streets, floors of a building, and certain types of transport.

At is used for specific points or locations, such as an address, a meeting place, or a destination.

A helpful way to think about these three is from large to small. In contains. On touches a surface. At marks a precise point.

Common Prepositions of Time

Prepositions of time tell when something happens. The same three words, in, on, and at, are also used for time, but each one applies to a different type of time expression.

In is used with months, years, seasons, and parts of the day.

On is used with days of the week and specific dates.

At is used with clock times and certain fixed expressions.

Other Common Prepositions

Beyond in, on, and at, a number of other prepositions appear regularly at beginner level. Each one shows a specific relationship.

To shows direction or destination.

From shows a point of origin or starting place.

With shows accompaniment or the use of a tool or object.

For shows purpose, duration, or a recipient.

Of shows belonging, part of a whole, or connection.
