Convent girl in Dublin undecided (3)
I believe the answer is:
nun
'convent girl' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'in dublin undecided' is the wordplay.
'in' says the answer is hidden in the clue.
'NUN' is hidden within 'dublin undecided'.
Can you help me to learn more?
(Other definitions for nun that I've seen before include "eg Carmelite" , "Convent dweller" , "Woman respecting order" , "A palindromic lady in religious order" , "Devout woman" .)
