Common mistakes ❌ with confusing prepositions.

In English we use prepositions with time, space and also idiomatically with no obvious logic. Yes🤭, I can hear you 🙉 ​😄​​: “Why do you say on the bus​​​🚌​ but in the car ​​​​🚗​? It makes no sense!” “Why do you say at night, ​​​​​🌃​ but in the morning​​​​​🌅​? That’s crazy!” “Why do you say on television​​​​​📺​ when you’re talking about what you’re seeing AT the TV (that’s the French) or IN the TV (for the Portuguese speakers)?”

The thing is, English prepositions don’t always follow rules. Many learners try to translate directly, which leads to mistakes and a mistake can make you sound unnatural. Prepositions are tiny words, but they can change a sentence.

To make things clearer, let’s break down some typical preposition mix-ups with easy examples. ​​​​​​​​​​​​👇

Good at vs. Good in

  • She’s good in math.

  • She’s good at math. ​​​​​​🟰


We use
good at for skills or abilities. Are you good at English? ​​😁

Interested in vs. Interested by

  • I’m interested by history.

  • I’m interested in history. ​​​​​​🦖


Interested in is the correct collocation.

Married with vs. Married to

  • She’s married with a doctor.

  • She’s married to a doctor. ​​​​​​​🧑🏽⚕️


Married with means having children (e.g., married with two kids).

On the bus vs. In the bus

  • I’m in the bus.

  • I’m on the bus. 🚌


We say
on for public transport (bus, train, plane). In is used for cars and taxis.

At vs. In (places)

  • I’m in the airport now.

  • I’m at the airport now. ​​​​​​​​​🛫


Use
at for locations as points, in is correct but for locating someone inside spaces.

Wait for vs. Wait

  • I’m waiting you.

  • I’m waiting for you. ​​​​​​​​​​🫵🏻


We always need
for after wait when followed by a person or thing.

Discuss about vs. Discuss

  • We discussed about the problem.

  • We discussed the problem. ​​​​​​​​​​​😵💫


Discuss does not need a preposition. But we can have a discussion about something.

In conclusion, with a bit of attention and practice, these common mistakes can be easily avoided. Keep these tips in mind, and you’ll start using prepositions correctly and confidently.
