Junior barrister catching sun (3)
I believe the answer is:
orb
'sun' is the definition.
(I've seen this in another clue)
'junior barrister catching' is the wordplay.
'catching' indicates a hidden word.
'ORB' is hidden in the letters of 'junior barrister'.
(Other definitions for orb that I've seen before include "component of royal regalia" , "Part of royal regalia" , "Sphere for a sovereign" , "Spherical object or shape" , "Ornamental globe" .)
