Dependent prepositions

Fixed prepositions after verbs, adjectives and nouns (depend on, good at, afraid of, the reason for).

Dependent prepositions are the fixed prepositions that English requires after particular verbs, adjectives and nouns, and they must be learned as whole chunks because they almost never match the Azerbaijani equivalent word for word. After certain verbs the preposition is fixed: depend on, rely on, listen to, belong to, apologise for, succeed in, insist on, accuse someone of, congratulate someone on, remind someone of. After many adjectives the preposition is also fixed: good/bad at, afraid/scared of, interested in, proud of, keen on, fond of, similar to, responsible for, worried about, famous for, full of. Even nouns have favourite prepositions: the reason for, a solution to, an increase in, the cause of, an answer to, interest in. The tricky part is that one English word can take different prepositions with different meanings (good at maths vs good for you; agree with a person vs agree to a plan), so context decides the choice. Note also that after any preposition a verb must be in the -ing form. For example: 'She is very good at chess and never gets bored of practising.'

🚫Common mistake

'Depend' and 'rely' are never followed by 'of' or 'in' — the fixed preposition is always 'on': depend on, rely on.

🚫Common mistake

Do not say 'similar with', 'full with' or 'responsible with'. The fixed pairs are similar to, full of and responsible for.

🚫Common mistake

After a preposition use the -ing form, not the infinitive: say 'insist on coming' and 'afraid of speaking', never 'insist to come' or 'afraid to speak'.

⚠️Caution

These are fixed combinations to memorise as chunks, because they rarely match the word-for-word translation. Watch meaning pairs: good at a skill but good for your health; remind someone of a memory but remind someone about a future task.
