The small words that follow common adjectives

interested in - good at - afraid of

How to use this sheet

Certain adjectives come with a fixed small word after them, and the pair works as a single unit - the small word carries no meaning of its own and cannot be worked out from logic or from your own language. Learn the pair together, as one vocabulary item, the way you would learn a new word. When a verb follows the pair, it takes the -ing form, never the to-form.
Middle column: the fixed small word that belongs to the adjective in the first column. The example shows the pair working as one unit inside a sentence.

Do not translate the small word from your own language - the English choice rarely matches, and row 7 is the classic trap because most languages use their word for accompaniment there, while English uses a direction word instead. Whenever you learn a new adjective, write down its partner word at the same time; guessing later almost always fails.
