Preposition Usage
Preposition choice is partly semantic and partly lexical. Learn common spatial and temporal meanings, but also learn the combinations that individual verbs, adjectives, and nouns conventionally take. Similar prepositions are not freely interchangeable, and register or dialect can affect some choices.
Choose a preposition from the relationship and the construction, not from a one-word translation rule. Prepositions can express place, time, direction, cause, means, and abstract relationships, and many verbs, adjectives, and nouns prefer particular preposition combinations. When a combination is uncertain, check a current dictionary or grammar reference for that exact expression.

Complements
A preposition is followed by a complement such as a noun phrase, pronoun, or another allowed structure. Distinguish this use from particles in phrasal verbs and from conjunction uses of the same word form.
Dictionary Check
When two choices both seem plausible, look up the exact adjective, noun, or verb plus preposition in a current dictionary or corpus-based grammar instead of guessing from a synonym.
Meaning First
Start with the relationship you need to express—location, movement, time, support, cause, method, comparison, or another relation—then check whether the construction has an established pattern.
Word Specific Patterns
Learn combinations as units when necessary: “interested in,” “responsible for,” and “depend on” are not generated reliably by a universal preposition formula.
Worked Example
“Different from” and “responsible for” show why substitution fails: the relation and the lexical pattern decide the preposition. Replacing either with an arbitrary near-synonym preposition produces unnatural English.
