Catcall coming from the French after card game (7)
I believe the answer is:
whistle
'catcall' is the definition.
(thesaurus)
'the french after card game' is the wordplay.
'the french' becomes 'le' ('the' in French).
'after' is a charade indicator (letters next to each other).
'card game' becomes 'whist' (whist is a kind of card game).
'le' put after 'whist' is 'WHISTLE'.
'coming from' acts as a link.
(Other definitions for whistle that I've seen before include "Pucker up and blow" , "Hits Lew to make shrill sound" , "L.S.White (anag.)" , "Make cheerful sound" , "Call vainly for" .)
