Moon goddess from Indian area (5)
I believe the answer is:
diana
'moon' is the definition.
(thesaurus)
'goddess from indian area' is the wordplay.
'goddess' becomes 'dian' (I have seen 'literary goddess' mean 'dian' so perhaps 'goddess' could also mean 'dian').
'from' means one lot of letters go next to another.
'indian area' becomes 'a' (maths abbreviation. I am not sure about the 'indian' bit.).
'dian'+'a'='DIANA'
Can you help me to learn more?
(Other definitions for diana that I've seen before include "female" , "Roman equivalent of Artemis" , "Roman goodess of hunting or tragic English princess" , "Roman goddess equating to Artemis" , "Roman goddess of the moon and the hunt" .)
