After that, he named her goddess of wisdom within (6)
I believe the answer is:
athena
'after that he named her goddess of wisdom within' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'after that he named her goddess of wisdom within' is the wordplay.
'ATHENA' is hidden within the letters.
But, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for athena that I've seen before include "Greek goddess of wisdom etc." , "Greek goddess of a capital city" , "One-time goddess" , "wise but fierce goddess" .)
