Reportedly sister's responsibilities in game (8)
I believe the answer is:
patience
'game' is the definition.
(I know that Patience is a patience)
'reportedly sister's responsibilities in' is the wordplay.
I cannot quite understand how this works, but
'reportedly' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'in' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for patience that I've seen before include "there's no one else to play this game" , "Card game played by one person" , "Card came for one" , "Waiting without complaint" , "likely to be lost by the hot-tempered" .)
