Give applause (4)
I believe the answer is:
hand
I believe this is a double definition.
'give' is the first definition.
(synonyms)
'applause' is the second definition.
(hand is a kind of applause)
(Other definitions for hand that I've seen before include "Manual worker" , "Crew member" , "Worker - penmanship - four inches" , "writing" , "Script" .)
