French word for 'test (3)
I believe the answer is:
mot
I believe this is a double definition.
'french word' is the first definition.
(I've seen this in other clues)
''test' is the second definition.
(as in an MOT test for a vehicle)
'for' acts as a link.
(Other definitions for mot that I've seen before include "Clever remark" , "Witty words" , "type of test" , "Vehicle check" , "A French word, may be bon" .)
