Goddess is tamer, somehow (7)
I believe the answer is:
artemis
'goddess' is the definition.
(Greek goddess)
'is tamer somehow' is the wordplay.
'somehow' is an anagram indicator.
'is'+'tamer'='istamer'
'istamer' is an anagram of 'ARTEMIS'.
(Other definitions for artemis that I've seen before include "Greek huntress goddess" , "female Olympian" , "Huntress daughter of Zeus" , "Greek goddess of the hunt" , "Mythical Greek huntress" .)
