Bishop endures reprimands (6)
I believe the answer is:
blasts
'reprimands' is the definition.
'bishop endures' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'endures' becomes 'lasts' ('last' can be a synonym of 'endure').
'b'+'lasts'='BLASTS'
(Other definitions for blasts that I've seen before include "Attacks vituperatively" , "Explosions" , "curses" .)
