Series of calls for applause (5)
I believe the answer is:
round
This clue is a double definition.
'series of calls' is the first definition.
(I've seen this before)
'for applause' is the second definition.
(round is a kind of applause)
(Other definitions for round that I've seen before include "... entire" , "Encircling" , "series of calls" , "Get applause" , "Lap" .)
