Seasoned judge leaving hurt (6)
I believe the answer is:
inured
'seasoned' is the definition.
(both can mean experienced)
'judge leaving hurt' is the wordplay.
'judge' becomes 'j' (abbreviation for judge).
'leaving' suggests deleting specific letters.
'hurt' becomes 'injured' (similar in meaning).
'injured' with 'j' removed is 'INURED'.
(Other definitions for inured that I've seen before include "Hardened against, toughened" , "Hardened against, emotion say" , "Hardened by familiarity" , "Habituated or hardened" , "Hardened, maybe ruined" .)
