Prepositions after adjectives

Peripheral to, in, for, of, or at?

Peripheral is most naturally followed by to when something is secondary or on the edge of something else. Other prepositions usually introduce separate context rather than fixed combinations.

Quick answer

Which preposition is used with peripheral?

Use peripheral to for something secondary, marginal, or connected to the outer edge of a subject or area.
