Fit, inhaling that French aroma (7)
I believe the answer is:
bouquet
'aroma' is the definition.
(bouquet is a kind of aroma)
'fit inhaling that french' is the wordplay.
'fit' becomes 'bout' (I've seen this in other clues).
'inhaling' means one lot of letters goes inside another.
'that french' becomes 'que' (French for 'that').
'bout' placed around 'que' is 'BOUQUET'.
(Other definitions for bouquet that I've seen before include "gets right up the wine taster's nose" , "aroma coming from tent?" , "Wine's aroma" , "A bunch of flowers in praise or compliment" , "Favourable comment" .)
