Go back and study in Mormon town (5)
I believe the answer is:
ogden
'mormon town' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'go back and study' is the wordplay.
'back' says the letters should be written in reverse.
'and' says to put letters next to each other.
'study' becomes 'den' (term for a study or office).
'go' in reverse letter order is 'og'.
'og'+'den'='OGDEN'
'in' is the link.
Can you help me to learn more?
(Another definition for ogden that I've seen is " ___ Nash, American poet".)
