Nose in fight broken by that Parisian (7)
I believe the answer is:
bouquet
'nose' is the definition.
(I've seen this before)
'fight broken by that parisian' is the wordplay.
'fight' becomes 'bout' (as in a bout in boxing).
'broken by' is an insertion indicator (inserted letters break into the word).
'that parisian' becomes 'que' ('that' in French).
'bout' placed around 'que' is 'BOUQUET'.
'in' is the link.
(Other definitions for bouquet that I've seen before include "Wine's aroma" , "Flower arrangement" , "Nosegay" , "Nose - flowers" , "aroma coming from tent?" .)
