Religious woman not affected by revolution (3)
I believe the answer is:
nun
'religious woman' is the definition.
(woman who has taken religious vows)
'not affected by revolution' is the wordplay.
I cannot quite understand how this works, but
'not' could be 'un' (prefix meaning 'not') and 'un' is located in the answer.
A single letter 'n' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nun that I've seen before include "One who's taken vows" , "Religious sister" , "Convent resident" , "Woman respecting order" , "A palindromic lady in religious order" .)
