Take part of judge in The Archers (4)
I believe the answer is:
hear
'take part of judge' is the definition.
(as in hearing a case like a judge)
'in the archers' is the wordplay.
'in' says the answer is hidden in the clue.
'HEAR' is hidden in the letters of 'the archers'.
(Other definitions for hear that I've seen before include "Be informed of" , "to judge" , "Perceive aurally" , "Hark" , "Discover aurally" .)
