Prepositions after adjectives

International: in, at, for, on, or with?

International usually describes something involving more than one country. The following preposition often depends on the noun or the rest of the sentence, not on international itself.

Quick answer

Does international take a fixed preposition?

International does not strongly select one preposition. You may see international in trade, international at the event, international for students, international on the committee, or international with partners, but the preposition usually belongs to the wider sentence.

She works in international trade.
The company is well known internationally for its research.
Delegates met at the international conference yesterday.
