Current in stream diverted deity (7)
I believe the answer is:
artemis
'deity' is the definition.
(Artemis is an example)
'current in stream diverted' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'in' is an insertion indicator.
'diverted' indicates an anagram (letters must be diverted to different positions).
'stream' is an anagram of 'artems'.
'i' placed within 'artems' is 'ARTEMIS'.
(Other definitions for artemis that I've seen before include "God" , "Olympian goddess of hunting" , "Virgin" , "Greek huntress goddess" , "Cynthia" .)
