Criticise expert getting a universal remedy (7)
I believe the answer is:
panacea
'universal remedy' is the definition.
(I've seen this before)
'criticise expert getting a' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'expert' becomes 'ace' (ace is a kind of expert**).
'getting' says to put letters next to each other.
'pan'+'ace'+'a'='PANACEA'
(Other definitions for panacea that I've seen before include "Universal cure" , "universal solution" , "wonder drug" , "A cure for everything" , "Solution to all difficulties" .)
