Adjective + Preposition: Good At, Interested In, Afraid Of

What this session covers

In English, many adjectives always take a specific preposition after them. 'Good' takes 'at' — 'I am good at football', never 'good in football' or 'good for football'. 'Interested' takes 'in' — 'She is interested in music', never 'interested of music'. These pairs are called dependent prepositions. They are not predictable from meaning — two similar adjectives can take completely different prepositions. 'Married' takes 'to' (married to my husband), but 'engaged' also takes 'to' (engaged to be married). 'Afraid' takes 'of' (afraid of spiders), but 'worried' takes 'about' (worried about the exam). Students must learn each adjective together with its preposition, as a single unit. This lesson introduces the most common adjective + preposition pairs at A2 level and gives teachers a practical way to drill them into active use.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
When a student says 'I am good in football' or 'interested of music', do you correct just the word, or do you teach the full chunk so the error does not return next week?
Q2
Which of these have you seen your students get wrong or avoid using altogether?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
She is good at English. ✓
She is good in English. ✗
She is good for English. ✗

He is interested in music. ✓
He is interested of music. ✗
He is interested about music. ✗

I am afraid of spiders. ✓
I am afraid from spiders. ✗
I am afraid about spiders. ✗

Each of these adjectives takes only one preposition after it. Why is it so hard for students to remember which one? And why can we not simply work out the preposition from the meaning?

The choice of preposition after an adjective is not logical — it is a fixed combination settled by use over time. 'At' in 'good at' does not mean the same as 'at' in 'at school'. 'In' in 'interested in' does not mean 'inside'. 'Of' in 'afraid of' does not mean the same as 'of' in 'one of my friends'. The preposition is part of the adjective's fixed pattern, not a separate word with its own meaning. This is why logic does not help — and why students must learn the adjective + preposition as a single chunk. 'Good at', 'interested in', 'afraid of' — these are three-word units, not two words plus a choice. Teaching them as chunks (like 'good_at' spoken as one unit) is the most effective approach.

Some adjectives use different prepositions to show different meanings:

worried about (= concerned) — I'm worried about my exam.
worried by (= the cause of worry) — I'm worried by the news.

good at (= skilled in) — She's good at maths.
good for (= beneficial) — Fruit is good for you.
good with (= able to handle) — He's good with children.

angry at / angry with (= at a person) — She's angry with me.
angry about (= about a situation) — She's angry about the decision.

Why do some adjectives have more than one preposition? And how should students choose the right one?

A few adjectives — 'good', 'worried', 'angry', 'sorry' — can take different prepositions depending on what follows and what meaning is intended. 'Good at' is about ability. 'Good for' is about benefit. 'Good with' is about handling something (usually people or animals). These are three different fixed patterns — not a choice a speaker makes each time, but three different idioms. Students need to learn the patterns separately: 'good at + activity', 'good for + person/thing', 'good with + person/animal'. This is more memorisation, but it is also how native speakers handle it — not by thinking, but by having the right chunk ready. At A2 level, teaching the most common version of each adjective ('good at', 'worried about') is enough; the other versions can come later.

Some adjectives take prepositions that students do not expect:

different FROM (not 'different than') — Her style is different from mine.
married TO (not 'married with') — He is married to a teacher.
full OF (not 'full with') — The room is full of books.
famous FOR (not 'famous of') — Paris is famous for its food.
kind TO (not 'kind with') — Be kind to animals.
ready FOR (not 'ready of') — Are you ready for the exam?

These particular adjectives cause trouble for learners from many different first languages. Why?

Each of these adjectives takes a preposition that does not match the most common translation from other languages. Many languages use 'with' for 'married', 'than' for 'different', 'of' for 'full'. English uses 'to', 'from', and 'of' respectively. Students who translate directly from their first language almost always produce errors here. The solution is explicit teaching and drilling — students need to meet 'different from' as a fixed chunk many times before it overwrites the translated version from their first language. Writing the adjective + preposition together on the board, saying them together, writing them together in notebooks — the more contexts the pairing appears in, the more likely the correct version becomes automatic.

The Pattern — What You Just Discovered

Many English adjectives take a specific preposition after them. The combination is not predictable from meaning — it must be learned as a fixed chunk. At A2 level, the most important pairs are: good at, interested in, afraid of, proud of, worried about, excited about, different from, married to, kind to, ready for, famous for, full of. Teaching these as single three-word units (not two separate words) is the most effective approach. Students who know the chunks produce natural English; students who guess from logic produce errors like 'good in' or 'interested of'.
Adjective Preposition Example Notes
good at She is good at maths. 'Good at' = skilled in. Different from 'good for' (beneficial) and 'good with' (able to handle).
interested in He is interested in history. 'Interested of' is a very common error — always 'in'.
afraid of The child is afraid of dogs. 'Afraid from' is wrong — always 'of'. Also: 'scared of', 'frightened of'.
proud of I am proud of my students. 'Proud of' for people, work, achievements. Not 'proud about' or 'proud for'.
worried about She is worried about her exam. 'Worried about' = concerned about something. 'Worried by' = made anxious by a specific cause.
excited about The children are excited about the trip. 'Excited for' is possible but 'excited about' is more standard for events and situations.
different from Her accent is different from mine. 'Different than' is American but not standard British. 'Different to' also exists but 'from' is safest.
married to He is married to a doctor. 'Married with' is a very common error — always 'to'. 'Engaged to' follows the same pattern.
kind to Please be kind to the new student. 'Kind to' (about behaviour towards someone). 'Kind of' is a different phrase (a type of).
ready for Are you ready for the lesson? 'Ready for + noun' or 'ready to + verb'. Not 'ready of'.
famous for Nigeria is famous for its music. 'Famous for + reason'. 'Famous as' is used with a role (famous as a writer).
full of The glass is full of water. 'Full with' is a direct translation from other languages but wrong in English — always 'of'.
Usage Notes

NOTE 1 — Adjective + preposition is a chunk: Teach these pairs as a single unit, not as two separate words. When a student meets 'interested', they should learn it with 'in' attached. When they write it in their vocabulary notebook, the preposition should be there too. Students who memorise chunks retrieve them automatically; students who memorise the adjective alone have to guess the preposition every time.

NOTE 2 — Translation traps: Some adjective + preposition pairs are predictable for many students; others are not. 'Married to' (not 'married with'), 'different from' (not 'different than' or 'different of'), 'full of' (not 'full with'), 'worried about' (not 'worried for') — these four cause trouble for students from many first languages. They need focused drilling.

NOTE 3 — Same adjective, different prepositions: A few common adjectives take different prepositions to show different meanings. 'Good at' (ability) / 'good for' (beneficial) / 'good with' (handle well). 'Angry with a person' / 'angry about a situation'. 'Sorry for a person' (feel pity) / 'sorry about a situation' (apology) / 'sorry to + verb' (regret). For A2 level, teach the most common version first; the others can come at B1.

NOTE 4 — Spoken practice matters most: Adjective + preposition errors are mostly speaking errors — in writing, students have time to check. In speech, the wrong preposition comes out because the right one is not automatic. Oral drilling — repeating 'good at', 'interested in', 'afraid of' in short sentences many times — is more effective than written exercises for fixing these into automatic use.

NOTE 5 — Build a personal chunk list: Each student should keep a list in their vocabulary notebook of every adjective + preposition pair they meet, with an example sentence. Over the term, this list grows into a personal reference. Reviewing it weekly and testing each other in pairs keeps the pairs active.

Note

Adjective + preposition errors are among the most frequent at A2 and B1 levels, and they continue into higher levels if not fixed early. They do not prevent communication — a listener can understand 'I am interested of music' — but they immediately mark the speaker as a non-fluent learner. The good news is that the number of common pairs is small. The 20 or 30 most frequent adjective + preposition pairs cover most everyday situations, and they can be taught systematically over a few lessons. The key principles are: teach them as chunks, drill them orally, and review them regularly until retrieval is automatic. Students who know 'good at' as one unit will never say 'good in'.

💡

Build a classroom adjective + preposition wall. Each time students meet a new pair in reading or class, they add it to the wall: ADJECTIVE + PREPOSITION with a short example. Review the wall at the start of each lesson for two minutes. The repeated exposure — even passive — fixes the pairs into memory more effectively than a single lesson can.

Common Student Errors

I am good in English but bad in maths.
I am good at English but bad at maths.
Why'Good at' and 'bad at' are the fixed collocations for skill or ability in a subject. 'Good in' and 'bad in' are very common errors — the preposition is always 'at' for this meaning.
She is interested of music and sport.
She is interested in music and sport.
Why'Interested' always takes 'in', never 'of'. 'Interested of' is one of the most common preposition errors at A2 and B1 level and comes from direct translation.
He is afraid from big dogs.
He is afraid of big dogs.
Why'Afraid of' is the fixed combination. 'Afraid from' is a translation error — in English, fear takes 'of'. The same pattern applies to 'scared of', 'frightened of', 'terrified of'.
My teacher is married with a doctor.
My teacher is married to a doctor.
Why'Married to' is the fixed preposition for this relationship. 'Married with' is one of the most persistent preposition errors because many languages use 'with'. Drill 'married to' until it is automatic.
The classroom is full with books.
The classroom is full of books.
Why'Full of' is the fixed phrase for describing what fills a container or space. 'Full with' is wrong in this meaning. (Note: 'filled with' does exist, e.g. 'the room was filled with smoke'.)

Check Your Understanding — Part 1

Choose the correct preposition to complete each sentence. Each adjective takes one specific preposition.

My sister is very good ___________ drawing — her pictures are always beautiful.
The students are very interested ___________ learning about other countries.
Many children are afraid ___________ the dark, even as they get older.
The head teacher is married ___________ a mathematics professor at the local university.
The children are very excited ___________ the school trip next week.

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence has a wrong preposition after the adjective. Find the error, write the correct sentence, and explain the rule.

My grandfather is very proud from his garden — he grows all our vegetables.
Write the correct sentence:
Explain why it is wrong:
My grandfather is very proud of his garden — he grows all our vegetables.
'Proud of' is the fixed combination for things, people, and achievements we are proud about. 'Proud from' is a direct translation error and never correct in English.
The shop is full with customers every Saturday morning.
Write the correct sentence:
Explain why it is wrong:
The shop is full of customers every Saturday morning.
'Full of' is the fixed phrase. 'Full with' is wrong — even though many languages use 'with' here, English uses 'of'. This is one of the most common preposition errors.
Please be kind with the new student — she is nervous about starting school.
Write the correct sentence:
Explain why it is wrong:
Please be kind to the new student — she is nervous about starting school.
'Kind to' is the fixed preposition for behaviour towards someone. 'Kind with' is wrong. Remember: we are kind TO people, TO animals, TO strangers.
Her writing style is very different than her sister's.
Write the correct sentence:
Explain why it is wrong:
Her writing style is very different from her sister's.
'Different from' is the standard combination in British English. 'Different than' is common in American English but should be avoided in formal British English. 'Different to' also exists but 'from' is the safest choice.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — What is a chunk? (4 min): Write 'good' on the board. Ask students: 'good what?' Elicit 'good at'. Then write 'at' next to 'good' to make 'good at'. Say: this is not two words — it is one chunk. You must always learn them together. Show four more examples: interested in, afraid of, proud of, married to. Students repeat each as one unit.

2

STEP 2 — Drill the most common pairs (7 min): Write 8 adjective + preposition pairs on the board: good at / interested in / afraid of / proud of / worried about / excited about / different from / married to. Say each pair aloud — students repeat three times. Then call out just the adjective — students supply the preposition. Do this at speed. Errors are corrected immediately.

3

STEP 3 — Translation traps (6 min): Focus on the four most persistent errors: 'married with' ✗ / 'full with' ✗ / 'different than' ✗ / 'interested of' ✗. Write each wrong form, then cross it out and write the correct one underneath. Explain why each is wrong — 'married with' comes from direct translation, 'full with' too, 'different than' is American English only, 'interested of' comes from direct translation. Drill the correct forms three times each.

4

STEP 4 — Talk about yourself (4 min): Each student produces three true sentences about themselves using three different adjective + preposition pairs. 'I am good at…' / 'I am interested in…' / 'I am afraid of…' etc. Share in pairs. Partner checks: was the preposition correct? This forces active production.

5

STEP 5 — Review and extend (4 min): Introduce three more pairs students may not know: ready for, famous for, kind to. Students produce a sentence using each. Show the full set of 12 pairs on the board as the reference list. Tell students to add these to their vocabulary notebooks as chunks — adjective + preposition + example sentence together.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 Adjective + preposition wall (classroom display)
Create a wall display with the adjectives on the left and the prepositions on the right. Each time students meet a new pair in reading or class, they add it to the wall. Over weeks the wall fills up. Review the wall for two minutes at the start of each lesson — pointing to each pair and having students say it aloud. This repeated exposure is the main way students fix pairs into memory.
Example sentences
good → at
interested → in
afraid → of
proud → of
worried → about
excited → about
different → from
married → to
kind → to
ready → for
famous → for
full → of
2 Quick-fire preposition drill (oral)
Call out an adjective from the wall. Students must instantly supply the preposition and use it in a short sentence. Move quickly around the class. Errors are corrected and repeated. The speed of this drill is the point — it forces automatic retrieval.
Example sentences
Teacher: 'interested' → Student: 'in — I am interested in history'
Teacher: 'afraid' → Student: 'of — I am afraid of snakes'
Teacher: 'married' → Student: 'to — my aunt is married to a farmer'
3 Write two true sentences (vocabulary notebook activity)
Each lesson, ask students to pick two adjective + preposition pairs from the list and write one true sentence with each in their notebook. Over the term, each student builds a personal reference of chunks tied to their own life. This is more memorable than teacher-provided examples.
Example sentences
'I am good at cooking — I help my mother every evening.'
'My uncle is married to a nurse from Lagos.'
'I am interested in football — I watch every match.'
'My little brother is afraid of dogs.'

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Build the list of pairs further with more B1-level adjectives: aware of, sure of, capable of, similar to, responsible for, keen on, fond of, dependent on.
Teach verb + preposition pairs as the parallel lesson — listen to, depend on, agree with, belong to. These follow the same chunk principle.
Introduce adjectives that can take different prepositions for different meanings: good at / good for / good with; angry with / angry about; sorry for / sorry about / sorry to.
Practise adjective + preposition chunks in longer text — ask students to find all the pairs in a newspaper article or short reading. Spotting them in real text builds recognition, which supports retrieval.
Ask students to test each other in pairs: one reads the adjective, the other supplies the preposition and an example. Pair testing catches gaps that whole-class drilling misses.
What is the one change you will make next time you teach this vocabulary?

Key Takeaways

1 Many English adjectives take a specific preposition after them. These combinations are not predictable from meaning — they must be learned as fixed chunks.
2 The most important A2 pairs to memorise: good at, interested in, afraid of, proud of, worried about, excited about, different from, married to, kind to, ready for, famous for, full of.
3 The four most persistent errors are 'married with' (should be 'to'), 'full with' (should be 'of'), 'different than' (should be 'from' in British English), and 'interested of' (should be 'in'). These need focused drilling.
4 A few adjectives take different prepositions for different meanings: 'good at' (ability), 'good for' (beneficial), 'good with' (able to handle). Teach the most common version first, others later.
5 Teaching these pairs as single three-word units — not adjective + separate preposition — is the most effective approach. Students who know the chunks produce natural English automatically; students who guess from logic produce errors every time.
