Compassion gets bishop to run off in pain (9)
I believe the answer is:
heartburn
'pain' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'compassion gets bishop to run off' is the wordplay.
'compassion' becomes 'heart' (I've seen this in another clue).
'gets' is a charade indicator (letters next to each other).
'bishop' becomes 'B' (chess abbreviation).
'to' says to put letters next to each other.
'off' indicates an anagram.
'run' is an anagram of 'urn'.
'heart'+'b'+'urn'='HEARTBURN'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for heartburn that I've seen before include "Acid indigestion" , "Acidic reflux" , "Form of indigestion" , "Disorder" , "You'll get feeling of discomfort" .)
