Enthusiastic cry (4)
I believe the answer is:
keen
This clue is a double definition.
'enthusiastic' is the first definition.
(thesaurus)
'cry' is the second definition.
(thesaurus)
(Other definitions for keen that I've seen before include "Sharp - avid" , "cry" , "Quick" , "express sorrow" , "Avid, enthusiastic" .)
