Round of applause for writing (4)
I believe the answer is:
hand
I believe this clue is a double definition.
'round of applause' is the first definition.
(thesaurus)
'writing' is the second definition.
('hand' can refer to someone's handwriting)
'for' is the link.
(Other definitions for hand that I've seen before include "Unclenched fist" , "employee" , "Unit of equine measurement" , "Crew member" , "audience response?" .)
