What Is a Preposition? A Simple Guide with Examples

Prepositions are essential building blocks in English. They help us describe relationships between words—especially when talking about time, place, or direction. But they can be tricky for learners because English often uses them in fixed ways.

In this post, we’ll explain what prepositions are, how they work, and give you easy examples to boost your grammar skills.

 What Is a Preposition?

A preposition is a word that connects a noun or pronoun to other parts of the sentence. It shows a relationship—often about time, place, direction, or cause.

Example:
The book is on the table.
(“on” shows the relationship between book and table)

 Common Prepositions in English

Here are some of the most used prepositions in English:

  • Place: in, on, at, under, over, behind

  • Time: before, after, during, since, until

  • Direction: to, from, into, onto, out of

  • Other: for, by, with, about, without

 Types of Prepositions (with Examples)

1. Prepositions of Place

These describe where something is located.

  • The phone is on the desk.

  • He lives in London.

  • The keys are under the sofa.

Prepositional Phrases

 Common Mistakes with Prepositions

English prepositions don’t always follow logic. Here are a few mistakes to avoid:

  • ❌ “She is good in English” → ✅ “She is good at English”

  • ❌ “I arrived to the office” → ✅ “I arrived at the office”

  • ❌ “He depends in his friend” → ✅ “He depends on his friend”
