Creature of habit in Open University (3)
I believe the answer is:
nun
'creature of habit' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'in open university' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NUN' is hidden in the letters of 'open university'.
Can you help me to learn more?
(Other definitions for nun that I've seen before include "A palindromic holy woman" , "Woman in religious community" , "She's a member of a religious community" , "Religious sister" , "Woman respecting order" .)
