Professor Jones popular with divine huntress (7)
I believe the answer is:
indiana
'professor jones' is the definition.
(I've seen this in another clue)
'popular with divine huntress' is the wordplay.
'popular' becomes 'in' (something that's 'in' is fashionable).
'with' says to put letters next to each other.
'divine huntress' becomes 'diana' (I've seen this in another clue).
'in'+'diana'='INDIANA'
(Other definitions for indiana that I've seen before include "The Hoosier State" , "State south of Lake Michigan" , "___ Jones, Harrison Ford hero - US state" , "___ Jones, action hero created by George Lucas" , "member of 2 [THE STATES]" .)
