What to do when an organ is out of order (5)
I believe the answer is:
groan
'what to do' is the definition.
The definition suggests a singular noun which matches the answer.
'an organ is out of order' is the wordplay.
'is out of order' is an anagram indicator.
'organ' anagrammed gives 'GROAN'.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for groan that I've seen before include "Sound of pain or despair" , "Sound of one in pain" , "Expression of pain or disapproval" , "express disapproval" , "Complaint" .)
