Prepositions after adjectives

Separate with prepositions

Separate from is the standard adjective pattern for things that are divided or independent. Other prepositions have more specific uses.

Quick answer

Which preposition follows separate?

Use separate from to show division or independence. Separate into is common with grouping, while separate to is mainly found in some legal or formal contexts. Separate in and separate at usually introduce additional information rather than fixed adjective patterns.

The office is separate from the warehouse.
The students were divided into small groups.
The twins live separate from their parents.
