Deity moves around divine saint (7)
I believe the answer is:
goddess
'deity' is the definition.
(goddess is a kind of deity)
'moves around divine saint' is the wordplay.
'moves' becomes 'goes' (going is a kind of moving**).
'around' means one lot of letters goes inside another.
'divine' becomes 'dd' (divine can mean theologian eg Doctor of Divinity).
'saint' becomes 's'.
'goes' placed around 'dd' is 'goddes'.
'goddes'+'s'='GODDESS'
(Other definitions for goddess that I've seen before include "divinity" , "Female deity" , "Such as Venus" , "Say Athena" , "Eg, Aphrodite" .)
