Sunrise overwhelms knight with other Order members (4)
I believe the answer is:
nuns
'order members' is the definition.
(I've seen this in another clue)
'sunrise overwhelms knight with other' is the wordplay.
I cannot quite understand how this works, but
'knight' could be 'n' (chess abbreviation) and 'n' is found within the answer.
The remaining letters 'uns' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nuns that I've seen before include "Convent residents" , "women in order" , "Religious community members" , "Religious sisters" , "Retired women" .)
