not limited to; not only… but also ~
This pattern expresses that something is not confined to a certain scope, extending beyond it.
This construction highlights that an action, phenomenon, or scope goes beyond an initial or expected boundary. It carries a formal, written nuance and is common in news, essays, and reports. In speech, it sounds stiff, so it's better to use patterns like だけではなく or のみならず in casual conversation.
The literal meaning is 'not stopping at', which gives a sense of movement or expansion from one point to a wider range. It often pairs with expressions that show additional extent, such as も, まで, or にまで.
