Many adjectives in English are followed by a fixed preposition when combined with a noun or -ing form — and the preposition cannot be predicted from the meaning of the adjective alone. Afraid of, good at, interested in, responsible for, similar to, familiar with — these are fixed collocations that must be learned as whole units. While no single rule covers all cases, useful partial patterns exist: adjectives of ability often take at, adjectives of feeling often take about or of, adjectives of relationship often take with or to. This lesson covers the most important collocations and strategies for teaching and learning them.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
Is there a rule that predicts which preposition follows each adjective? Or must these be learned individually?
There is no single rule that reliably predicts which preposition follows a given adjective. Afraid of seems logical, but the preposition could theoretically have been afraid about, afraid from, or afraid with — and in some other languages, different prepositions are used for the equivalent adjective. The same is true for good at (why not good in or good for?), interested in (why not interested about?), and responsible for (why not responsible of?). These are fixed collocations — the adjective and its preposition have been fixed by convention over time. The practical implication for teaching is clear: learners should learn adjective + preposition as a whole unit, recording them together (afraid of, not just afraid), and using them in complete, meaningful phrases to help the combination stick in memory.
What connects the adjectives in each group? Is there a semantic pattern?
Partial patterns do exist. Of frequently follows adjectives of awareness, evaluation, or feeling about something: aware of, proud of, afraid of, tired of, fond of. At frequently follows adjectives of skill and performance: good at, bad at, skilled at, brilliant at. About frequently follows adjectives of emotional state or attitude toward a situation: worried about, excited about, nervous about, angry about. With frequently follows adjectives expressing relationship, satisfaction, or similarity: familiar with, satisfied with, pleased with. These patterns are not complete rules — exceptions exist (responsible for, not responsible of; interested in, not interested about) — but they reduce the learning load significantly. Teaching learners to notice these patterns helps them make educated guesses when they encounter new adjectives, and to organise their learning more efficiently.
He is good at teaching. (skill)
He is good for the school. (beneficial to)
The new approach is different from the old one. (British English)
The new approach is different to the old one. (informal British English)
The new approach is different than the old one. (American English)
What do these examples tell you about the relationship between preposition choice and meaning?
Some adjectives take different prepositions depending on the meaning or what follows. Angry about is used for situations and events; angry with is used for people. Good at is for ability; good for is for benefit. Different from is the traditionally standard British English form; different to is informal British; different than is American English. These preposition-sensitive meaning changes are important to know because they show that learning just one preposition for each adjective is sometimes insufficient — the full picture includes knowing which prepositions the adjective takes and what each combination means. For learners, the practical priority is learning the most common combination first, then extending to alternatives as proficiency develops.'
| Form | Use / Meaning | Example |
|---|---|---|
| Preposition | Typical adjective type | Examples |
| of | Awareness, evaluation, feeling about something | afraid of, aware of, proud of, tired of, fond of, ashamed of, capable of, full of |
| at | Skill and performance | good at, bad at, skilled at, brilliant at, hopeless at, quick at, slow at |
| about | Emotional state or attitude toward a situation | worried about, excited about, nervous about, serious about, angry about, happy about |
| with | Relationship, satisfaction, comparison | familiar with, satisfied with, pleased with, disappointed with, angry with (person), bored with |
| for | Suitability, purpose, gratitude | responsible for, suitable for, famous for, ready for, grateful for, eager for |
| to | Relationship, similarity, reaction | similar to, married to, related to, opposed to, relevant to, due to |
| in | Engagement, involvement | interested in, involved in, experienced in, qualified in, successful in |
INTERESTED IN VERSUS INTERESTING TO
Interested in and interesting to look similar but have different structures. She is interested in the topic (adjective + preposition + noun — she experiences interest). The topic is interesting to her (the topic causes interest, to her is optional). Interested in is the high-frequency collocation for expressing interest in something. Interesting to can also appear: It is interesting to compare these approaches. Both are correct but describe different things — the experiencer (interested in) and the cause of interest (interesting to).
ANGRY ABOUT VERSUS ANGRY WITH
The angry about / angry with distinction is important for professional communication. When writing about situations, decisions, or events, use angry about: She was angry about the decision. When writing about a person who has done something, use angry with: She was angry with her colleague. In informal speech, angry at is also used (especially in American English): She was angry at the result / angry at him. In formal writing, about (for situations) and with (for people) are the preferred choices.
CAPABLE OF VERSUS ABLE TO
Capable of and able to are both used to express ability, but their grammatical environments are different. Capable of is an adjective + preposition + -ing form: She is capable of managing the class alone. Able to is an adjective + to-infinitive: She is able to manage the class alone. Both mean the same thing but require different grammatical structures after them. Learners who know capable of must use -ing (not capable of to manage) are demonstrating real grammatical precision.
ADJECTIVE + PREPOSITION: QUICK GUIDE - Is it an awareness or feeling about something adjective? Try of: afraid of, aware of, proud of, tired of, ashamed of, capable of. - Is it a skill or performance adjective? Try at: good at, bad at, skilled at, hopeless at. - Is it an emotional state about a situation? Try about: worried about, excited about, nervous about, serious about. - Is it a relationship or satisfaction adjective? Try with: familiar with, satisfied with, pleased with, disappointed with. - Is it a suitability or responsibility adjective? Try for: responsible for, suitable for, ready for, grateful for. - Is there a verb after the adjective + preposition? Use -ing: good at teaching / afraid of making / responsible for organising.
Choose the correct preposition to complete each adjective + preposition collocation.
Each sentence has an error in an adjective + preposition collocation. Write the correct sentence and explain the mistake.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — WHY THESE CANNOT BE PREDICTED (5 minutes): Ask learners: if afraid takes of, why does worried take about and not of? If good takes at, why does interested take in and not at? Establish honestly that no rule covers all cases — these are fixed collocations that must be learned as whole units. But patterns can help. This framing prevents frustration and sets realistic expectations.
STEP 2 — THE PARTIAL PATTERNS (8 minutes): Introduce the four main pattern groups: of (awareness/feeling), at (ability), about (emotion/situation), with (relationship/satisfaction). Give three examples of each. Ask learners to add one more to each group from their own knowledge. Confirm each suggestion and note any exceptions that arise.
STEP 3 — PROFESSIONAL PHRASE FOCUS (8 minutes): Focus on the adjective + preposition collocations most useful for teachers: responsible for, interested in, familiar with, aware of, capable of, good at, proud of, worried about, pleased with, similar to, different from, ready for, suitable for, grateful for. Write these on the board. Ask learners to cover the prepositions and try to recall them. Discuss any that cause uncertainty.
STEP 4 — -ING AFTER ADJECTIVE + PREPOSITION (7 minutes): Write five sentences with a verb following an adjective + preposition (afraid of ___, good at ___, responsible for ___). Ask learners to complete each with either the -ing form or the to-infinitive. Confirm: after adjective + preposition, use -ing. This prevents a separate but very common error.
STEP 5 — PRODUCE IN CONTEXT (7 minutes): Ask learners to write five sentences about their professional life using adjective + preposition collocations. They must use at least three different prepositions. Share with a partner who checks: correct preposition? correct -ing form after the preposition if a verb follows?
Use directly in class — copy, adapt, or read aloud. No printing needed.
