Goddess who lives again? (4)
I believe the answer is:
isis
'goddess' is the definition.
(thesaurus)
'lives again?' is the wordplay.
'lives' becomes 'is' ('be' can be a synonym of 'live').
'again?' becomes 'is' (I can't justify this - if you can you should give a lot more credence to this answer).
'is'+'is'='ISIS'
'who' is the link.
Can you help me to learn more?
(Other definitions for isis that I've seen before include "Exists twice for a goddess" , "Egyptian deity" , "Part of river" , "A dark blue flower" , "Wife of Osiris" .)
