King in Polish tomb (6)
I believe the answer is:
shrine
'tomb' is the definition.
(shrine can mean a tomb or memorial)
'king in polish' is the wordplay.
I cannot quite see how this works, but
'king' could be 'r' (abbreviation of Latin rex) and 'r' is located in the answer.
'in' is present in the answer.
The remaining letters 'she' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shrine that I've seen before include "Holy place with special associations" , "Hallowed place associated with a sacred thing or person" , "here to pray?" , "burial place?" , "Tomb or monument of a saint" .)
