If you are preparing for English exams like IELTS, FCE, or other Cambridge tests, adjective and preposition combinations are everywhere. These little partnerships love appearing in grammar questions, sentence transformations, and multiple-choice tasks. One tiny preposition in the wrong place and suddenly the sentence looks completely wrong.
That is because many adjectives naturally stick to a specific preposition. Think of them like grammar best friends. Accustomed to, interested in, afraid of, good at. Swap the preposition and the sentence stops sounding natural.
Exams such as B1, B2, and C1 Cambridge English tests, as well as IELTS grammar sections, often check whether you recognise these combinations. They may ask you to complete a sentence, correct a mistake, or choose the right preposition from a list. It looks simple, but it is an easy place to lose marks if you are guessing.
The good news is that once you start noticing these adjective + preposition pairs, they become much easier to remember. Treat them as fixed phrases rather than trying to figure them out logically every time. Learn the pattern once, and suddenly a whole group of exam questions becomes much less scary.
