Wild tale about Frenchman (6)
I believe the answer is:
stormy
'wild' is the definition.
('stormy' can be similar in meaning to 'wild')
'tale about frenchman' is the wordplay.
'tale' becomes 'story' ('story' can be a synonym of 'tale').
'about' is an insertion indicator.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'story' going around 'm' is 'STORMY'.
(Other definitions for stormy that I've seen before include "Describes violent weather" , "''... Weather'' (old torch song)" , "Full of violent outbursts" , "The sort of weather unfavourable to sailors" , "Describes weather with force 11 winds" .)
