## Definition

almost fitting into a certain category, but not quite. You use it when something is on the edge between two states, like being healthy and sick.

For teachers: situated on the edge of a category or condition; not clearly belonging to one side or the other. Often used with 'on' to indicate proximity to a limit.

## Examples

- His health is borderline, so he needs rest.
- The company's profits were borderline, just enough to avoid a loss.
- Her performance was borderline, hovering between acceptable and disappointing, leaving the judges unsure whether to award her a place in the finals.

## Usage notes

- Often used predicatively after 'be' or attributively before a noun. Frequently paired with 'on' (e.g., 'borderline on genius').
