Everything you need to use fixed verb and adjective + preposition combinations correctly in English, with common mistakes and exam practice.
Many English verbs and adjectives are followed by one specific, fixed preposition, "depend ON," "interested IN," "good AT", and there's usually no logical reason for which preposition it is, it simply has to be learned alongside the verb itself. Using the wrong one doesn't just sound slightly off, it's often flagged as a clear, basic error, since native speakers have zero flexibility here: "depend of" or "depend from" simply isn't an option.
| Verb + Preposition | Example |
|---|---|
| depend on | It depends on the weather. |
| believe in | I believe in second chances. |
| apologise for | She apologised for being late. |
| listen to | We listened to the announcement carefully. |
| wait for | I'm waiting for the bus. |
| look for | I'm looking for my keys. |
| look after | Can you look after my dog this weekend? |
| think about / of | I've been thinking about the offer. |
| worry about | Don't worry about the results. |
| succeed in | She succeeded in passing the exam. |
| consist of | The team consists of five people. |
| complain about | He complained about the service. |
| deal with | I'll deal with it tomorrow. |
| insist on | He insisted on paying for dinner. |
| congratulate on | I congratulated her on the promotion. |
The same fixed-pairing principle applies to many common adjectives too.
| Adjective + Preposition | Example |
|---|---|
| interested in | I'm interested in learning Spanish. |
| good at / bad at | She's good at maths but bad at chemistry. |
| afraid of | He's afraid of spiders. |
| proud of | We're proud of your progress. |
| married to | She's married to a doctor. |
| similar to | This is similar to what we discussed. |
| responsible for | Who's responsible for this decision? |
| famous for | The city is famous for its architecture. |
| worried about | I'm worried about the exam. |
| keen on | He's quite keen on the idea. |
It's easy to confuse this topic with phrasal verbs, but they're structurally different. A phrasal verb's particle changes the verb's core meaning entirely (give up = quit, look up = search for information), often allowing the object to move around the particle. A verb + preposition combination keeps the verb's original meaning intact, the preposition just fixedly connects it to its object, with no meaning shift and no flexibility in word order.
| Type | Example | Meaning Shift? |
|---|---|---|
| Phrasal verb | She gave up smoking. | Yes, "give up" means "quit," unrelated to "give" |
| Verb + preposition | She depends on her parents. | No, "depend" keeps its normal meaning; "on" is just fixed |
| ❌ Incorrect | ✅ Correct | Why |
|---|---|---|
| It depends of the weather. | It depends on the weather. | "Depend" is fixedly paired with "on," never "of" or "from." |
| I'm interested on this topic. | I'm interested in this topic. | "Interested" takes "in," not "on." |
| Let's discuss about the plan. | Let's discuss the plan. | "Discuss" takes a direct object with no preposition at all. |
| She's married with a doctor. | She's married to a doctor. | "Married" is fixedly paired with "to." |
| I apologise about the delay. | I apologise for the delay. | "Apologise" is fixedly paired with "for." |
| Exam | How This Is Tested | Sample Question |
|---|---|---|
| Cambridge B1 Preliminary / B2 First | Fixed preposition choice is a classic Reading Part 5 open cloze pattern. | "She apologised ___ being late." (for) |
| IELTS Speaking & Writing | Accurate fixed prepositions signal natural, error-free control at higher bands. | Using "good at," "interested in" and "depend on" naturally across a range of topics. |
| Trinity GESE/ISE (SELT) | These combinations appear constantly in everyday conversational topics about interests and routines. | "What are you interested in?" |
