Applause for royal flush? (4)
I believe the answer is:
hand
I believe this clue is a double definition.
'applause' is the first definition.
(hand is a kind of applause)
'royal flush?' is the second definition.
(thesaurus)
'for' acts as a link.
(Other definitions for hand that I've seen before include "Player's cards" , "Pointer; workman" , "Help < and applause" , "that may be engaged in a shake" , "Cards dealt to player" .)
