Bishop with responsibility to provide blessing (5)
I believe the answer is:
bonus
'blessing' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'bishop with responsibility' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'with' is a charade indicator (letters next to each other).
'responsibility' becomes 'onus' (onus is a duty or responsibility).
'b'+'onus'='BONUS'
'to provide' is the link.
Can you help me to learn more?
(Other definitions for bonus that I've seen before include "Extra payment - reward" , "Additional incentive payment" , "Additional award" , "Sum added to salary for good performance" , "Honorarium" .)
