Unique person (3-3)

Ross

I believe the answer is:

one-off

'unique person' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for one-off that I've seen before include "Happening only once" , "Unique specimen" , "Item made once only" , "Unique person or occurrence" , "Made or done as a single thing, not repeated" .)

I've seen this clue in The Times.
