Form and rules
How it works
Common patterns include interested in, good/bad at, afraid of, responsible for and similar to.
After a preposition, a verb normally takes -ing: interested in learning.
Some adjectives allow more than one preposition with different meanings, so learn the full phrase.
People can be angry with someone and angry about/at something depending on meaning.
Do not translate prepositions directly from another language; treat the combination as a fixed pattern.
