Preposition Mistakes
Preposition mistakes are the hardest to catch in your own speech. Good at — not good in. Learn the most common wrong prepositions and the correct ones to replace them with.
Simple explanation
Prepositions are small words like in, on, at, with, for, about — and English has very fixed habits about which preposition goes with which word. These habits do not always match other languages, which is why preposition mistakes are so common and so hard to notice.
Why it matters
Preposition mistakes do not usually cause confusion about meaning — but they do create a feeling that something is off in the sentence. Fixing the most common ones makes your English feel natural and effortless.
The most common preposition errors
1. "Good in" vs "Good at"
Skill or ability → always use at. Good at, bad at, excellent at, poor at.
2. "Discuss about"
Discuss already means "talk about." Adding about is redundant — remove it entirely.
3. "Cope up with"
There is no up in cope with. Remove it.
4. "Married with" vs "Married to"
5. "Bored of" vs "Bored with"
6. "At the morning" vs "In the morning"
Parts of the day use in: in the morning, in the afternoon, in the evening. Use at only for clock times and at night.
Fixed preposition pairs to memorise
| Say this | Not this |
|---|---|
| good at something | |
| discuss the topic | |
| cope with pressure | |
| married to someone | |
| in the morning/afternoon/evening | |
| arrive at a place | |
| afraid of something | |
| different from something | |
| depend on someone | |
| interested in something |
How to learn the right prepositions
Because prepositions are not always logical, the best strategy is to learn them attached to the word they go with — not in isolation. Learners who try to memorise a list of prepositions alone often forget them. Learners who remember the whole phrase (good at, interested in, cope with) remember it much longer.
Here is a simple method that works:
Pick one wrong pair per week. Look at the table above and pick the pair you use incorrectly most often. Write the correct version on a sticky note or your phone's lock screen. Every time you see it, say the correct version aloud. By the end of the week, it will feel unnatural to say it wrong.
Do not try to fix all ten pairs at once. One per week means ten correct preposition habits in ten weeks — permanent, not memorised and forgotten.
Also, when you learn a new English verb or adjective, look up which preposition it uses. Some dictionaries list it. A quick search like "interested in or interested on" takes five seconds and saves weeks of using the wrong one.

Quick summary
- Skill/ability → good at, not good in.
- Discuss needs no about — it already means "talk about."
- Cope with, not cope up with.
- Parts of the day → in (in the morning, in the evening). Clock times → at.
Pick one pair from the table above — the one you know you use incorrectly. Write it on a sticky note. Put it where you can see it. Catch yourself this week. One preposition fixed and remembered is more valuable than ten rules memorised and forgotten.
