Dependent Prepositions (adjectives)
B1 IntermediateDependent prepositions are specific words that must follow certain adjectives to connect them to a noun or pronoun. Learning these fixed pairs helps you speak and write more naturally in English.
Overview
In English, many adjectives are followed by a specific preposition. These are called dependent prepositions because the choice of preposition depends entirely on the adjective that comes before it. There is often no logical rule for why a specific preposition is used, so it is best to learn them as fixed pairs.
Form
subject + be + adjective + preposition + object
The preposition connects the adjective to an object, which can be a noun, a pronoun, or a gerund (-ing form).
