Faith's back at university (5)
I believe the answer is:
hindu
'faith's' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'back at university' is the wordplay.
'back' becomes 'hind' (synonyms).
'at' means one lot of letters go next to another.
'university' becomes 'U' (abbreviation as in UMass).
'hind'+'u'='HINDU'
Can you help me to learn more?
(Other definitions for hindu that I've seen before include "Follower of India's main religion" , "Member of religious group" , "Eastern believer" , "Person with faith" , "Man of religion" .)
