Medic, one the French find submissive (6)
I believe the answer is:
docile
'submissive' is the definition.
(I've seen this before)
'medic one the french' is the wordplay.
'medic' becomes 'doc' (I've seen this before).
'one' becomes 'i' (Roman numeral).
'the french' becomes 'le' ('the' in French).
'doc'+'i'+'le'='DOCILE'
'find' acts as a link.
(Other definitions for docile that I've seen before include "Coiled in obedient way" , "Tame, biddable" , "Willing to obey, not aggressive" , "Gentle and biddable" , "Easily managed and trainable" .)
