Here in France, head shows hostile attitude (7)
I believe the answer is:
iciness
'hostile attitude' is the definition.
(I've seen this before)
'here in france head' is the wordplay.
'here in france' becomes 'ici' ('here' in French).
'head' becomes 'ness' (ness is a headland).
'ici'+'ness'='ICINESS'
'shows' acts as a link.
(Other definitions for iciness that I've seen before include "Extreme cold" , "Unapproachability" , "Extreme hostility" , "Hostility, unfriendliness" , "Such weather" .)
