Glow surrounding king’s darga (6)
I believe the answer is:
shrine
'darga' is the definition.
I can't judge whether this defines the answer.
'glow surrounding king's' is the wordplay.
'glow' becomes 'shine' (synonyms).
'surrounding' is an insertion indicator.
'king' becomes 'R' (abbreviation for rex, king in Latin).
'shine' enclosing 'r' is 'SHRINE'.
Can you help me to learn more?
(Other definitions for shrine that I've seen before include "Pilgrim's destination" , "here to pray?" , "Holy place with special associations" , "burial place?" , "Casket with holy relics" .)
