Reveal a Parisian caught by Kent port not opening (7)
I believe the answer is:
uncover
'reveal' is the definition.
(synonyms)
'a parisian caught by kent port not opening' is the wordplay.
'a parisian' becomes 'un'.
'caught' becomes 'c' (cricket abbreviation).
'by' is a charade indicator (letters next to each other).
'kent port' becomes 'dover' (I've seen this before).
'not opening' means to remove the first letter (the opening letter is removed).
'dover' with its first letter taken off is 'over'.
'un'+'c'+'over'='UNCOVER'
(Other definitions for uncover that I've seen before include "Take the lid off" , "Make visible" , "make a revelation" , "Expose, unveil" , "show?" .)
