Cease endless confusion of experts (4)
I believe the answer is:
aces
'experts' is the definition.
(ace is a kind of expert)
'cease endless confusion' is the wordplay.
'endless' means to remove the last letter.
'confusion' indicates an anagram.
'cease' with its final letter taken off is 'ceas'.
'ceas' with letters rearranged gives 'ACES'.
'of' acts as a link.
(Other definitions for aces that I've seen before include "winning points" , "holes in one" , "Top cards or people" , "Honours" , "Unreturnable services" .)
