Intimidate a Parisian with bottle (7)
I believe the answer is:
unnerve
'intimidate' is the definition.
(unnerve can mean to intimidate or scare)
'a parisian with bottle' is the wordplay.
'a parisian' becomes 'un' ('a' in French).
'with' is a charade indicator (letters next to each other).
'bottle' becomes 'nerve' (both can mean courage).
'un'+'nerve'='UNNERVE'
(Other definitions for unnerve that I've seen before include "Dishearten - discourage" , "Discourage - demoralise" , "Make one get in a fluster" , "Deprive of courage" , "Cause to lose courage - even run away" .)
