Prepositions in English: Rules, List, and Common Mistakes

Prepositions are small words that cause big problems — even advanced learners regularly say "married with" instead of "married to," or "depend of" instead of "depend on." Unlike most grammar, prepositions often don't follow logical rules; they follow usage, which means the fastest way to master them is exposure plus targeted practice.

What Is a Preposition?

A preposition shows the relationship between a noun (or pronoun) and another word in the sentence — usually relating to time, place, or direction.

The book is on the table. (place) I'll see you at 6pm. (time) She walked into the room. (movement)

Prepositions of Time

• at — for precise times: at 6pm, at noon, at midnight
• on — for days and dates: on Monday, on July 4th
• in — for longer periods: in July, in 2024, in the morning

Prepositions of Place

• at — a specific point: at the door, at the station
• on — a surface: on the table, on the wall
• in — an enclosed space: in the box, in the room, in London

Prepositions of Movement

to, into, onto, through, across, along, past, over, under

She walked through the park and across the bridge.

Common Preposition + Verb Combinations

These pairings don't follow logical rules and simply need to be memorized:

• depend on
• listen to
• wait for
• believe in
• apologize for
• married to (not "with")
• good at (not "in")
• interested in

Common Mistakes with Prepositions

1. "Married with" instead of "married to"
2. "Discuss about" — "discuss" doesn't need a preposition ("discuss the issue," not "discuss about the issue")
3. "Depend of" instead of "depend on"
4. Confusing "in," "on," and "at" for time and place

Prepositions and Passive Voice

Prepositions frequently appear in passive constructions to introduce the agent: "The award was given by the committee." Understanding this pairing helps when converting between active and passive voice — see our active and passive voice guide for more.

FAQ

Why are prepositions so hard to learn? Because their usage is often based on convention rather than logic, and it varies between languages — a preposition that's correct in one language often doesn't translate directly into English.

What's the best way to memorize prepositions? Learn them attached to specific verbs and phrases ("depend on," "good at") rather than in isolation, and get exposure through reading and listening.

Do native speakers ever make preposition mistakes? Rarely with common combinations, but regional variation exists (e.g., "different from" vs "different than" vs "different to").
