Bishop's in helping disheartened lady nonstop (9)
I believe the answer is:
abidingly
'nonstop' is the definition.
Both the definition and answer are adverbs.
Maybe they are linked in a way I don't understand?
'bishop's in helping disheartened lady' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'in' is an insertion indicator.
'helping' becomes 'aiding' ('aid' can be a synonym of 'help').
'disheartened' suggests removing the centre.
'lady' with its middle taken out is 'ly'.
'b' placed inside 'aiding' is 'abiding'.
'abiding'+'ly'='ABIDINGLY'
Can you help me to learn more?
(Another definition for abidingly that I've seen is " in the long term".)
