A perfect term of French (3,5)

Ross

I believe the answer is:

mot juste

'a perfect term of french' is the definition.
('mot juste' means the perfect word in French)

This is the entire clue.

(Other definitions for mot juste that I've seen before include "Exactly appropriate word" , "Highly appropriate expression" .)

I've seen this clue in The Guardian.
