She makes a point repeatedly about being superior (3)
I believe the answer is:
nun
'she' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'a point repeatedly about being superior' is the wordplay.
'a point' becomes 'N' (N is an example).
'repeatedly' indicates the doubling of some letters.
'about' means one lot of letters goes inside another.
'being superior' becomes 'u' (U can mean upper-class, as in U and non-U speech).
'n' duplicated is 'nn'.
'nn' enclosing 'u' is 'NUN'.
'makes' is the link.
Can you help me to learn more?
(Other definitions for nun that I've seen before include "Carmelite, for example" , "whose son entered Promised Land" , "Letter" , "Religious woman, a palindrome" , "Religious sister" .)
