Prepositions after adjectives

Official with, in, for, on, or at?

Official is commonly followed by for in roles and responsibilities. Other prepositions are possible in different sentence structures, but not all combinations directly belong to the adjective official.

Quick answer

Which preposition is used with official?

The most common pattern is official for when someone has responsibility for something. Official in is also used for membership or participation in an organisation or activity. Official with is uncommon and usually means dealing with a person or organisation, not a fixed adjective pattern. Official on and official at are normally followed by extra information about place or topic rather than selected by the adjective itself.

She is the government official for public health policy.
He became an official in the trade union.

1

Showing responsibility or authority

Use official for to describe the area, event, or duty someone is responsible for.

Confusing official for with official in
