Adjectives and Prepositions
Learn common adjective and preposition combinations such as interested in, good at, afraid of, and responsible for.
Learning Objective
Adjectives and Prepositions
Use frequent adjective–preposition combinations accurately in simple descriptions and conversations.
Clear Explanation
Many adjectives are conventionally followed by a particular preposition. The combination must usually be learned as a unit because the preposition is not freely interchangeable.
Form and Structure
adjective + preposition + noun / pronoun / verb-ing
“Maya is interested in photography.”
There is no single rule that predicts every adjective–preposition pairing. Notice the combination in context and record it as one phrase.
Meaning and Use
Common combinations
Learn the adjective together with its preposition: good at, afraid of, interested in, and responsible for.
“Leo is good at solving puzzles.”
After the preposition
Use a noun, an object pronoun, or an -ing form after the preposition.
“She is excited about travelling.”
Meaning can change
Different prepositions can create different meanings, so check the complete phrase.
“I am sorry about the delay, and I am sorry for causing it.”
Common Errors and Meaning Traps
She is interested on science.
She is interested in science.
Interested normally takes the preposition in.
He is good in chess.
He is good at chess.
Use good at for skill in an activity.
We are responsible to booking the room.
We are responsible for booking the room.
Responsible for is followed here by the -ing form booking.
