Appropriate Preposition Guide

What Is an Appropriate Preposition?

A preposition shows the relationship between a noun (or pronoun) and other words in a sentence—often indicating direction, place, time, or method. Choosing the appropriate preposition is essential for clear and correct English communication.

Common Prepositions & Their Uses

• at – specific time or point (She arrived at 5 PM.)
• on – surfaces or days (The book is on the table. We met on Monday.)
• in – enclosed spaces or longer periods (He lives in Paris. She was born in 1990.)
• by – agent in passive voice or means (The song was written by Taylor. I traveled by train.)
• with – accompaniment or instrument (She went with her friend. He cut it with a knife.)

3. ❌ “Angry for” → ✅ “Angry with (someone) / Angry about (something)”
