Snappy greeting between clubs repeated (4)
I believe the answer is:
chic
'snappy' is the definition.
(thesaurus)
'greeting between clubs repeated' is the wordplay.
'greeting' becomes 'hi' (hi is a kind of greeting).
'between' means one lot of letters goes inside another.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'repeated' indicates the doubling of some letters.
'c' duplicated is 'cc'.
'hi' inserted inside 'cc' is 'CHIC'.
(Other definitions for chic that I've seen before include "Trendy" , "Fashionable good taste" , "Snazzy" , "Stylishly turned out" , "French elegance" .)
