にとどまらず

にとどまらず means "not limited to," "not stopping at," or "not only… but also." It expresses the idea that something goes beyond a certain scope or boundary, extending further than expected. It comes from the verb とどまる (to remain, to stay at), combined with the negative form ず (classical negative), creating the meaning of "not remaining at" or "not being confined to."

This is a formal, written expression commonly found in news articles, academic writing, business contexts, and formal speeches. It emphasizes that the extent or influence of something surpasses an initial range.

Basic Usage

The pattern attaches to nouns (sometimes with particles) to indicate the starting scope that is then exceeded.

にとどまらず vs. だけでなく

Both にとどまらず and だけでなく convey "not only… but also," but にとどまらず carries a stronger nuance of expansion beyond a boundary and is more formal. だけでなく is more neutral and can be used in everyday conversation, while にとどまらず is primarily used in written or formal contexts.

Common Patterns

にとどまらず is often followed by expressions like 〜～も, 〜～にも, or 〜～まで to indicate the extended scope.
