Answer given by department's experts (6)
I believe the answer is:
adepts
'experts' is the definition.
(adept is a kind of expert)
'answer given by department's' is the wordplay.
'answer given' becomes 'a' (abbreviation eg in Q and A. I am not sure about the 'given' bit.**).
'by' is a charade indicator (letters next to each other).
'department's' becomes 'depts'.
'a'+'depts'='ADEPTS'
Can you help me to learn more?
(Other definitions for adepts that I've seen before include "Pasted by experts" , "Pasted by skilled people" , "Expert or skilled people" , "Virtuosos, hotshots" , "People with talent" .)
