Medicine in Asia Galen produced (9)
I believe the answer is:
analgesia
'medicine' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'in asia galen produced' is the wordplay.
'in' is an insertion indicator.
'produced' is an anagram indicator.
'galen' is an anagram of 'nalge'.
'asia' going around 'nalge' is 'ANALGESIA'.
Can you help me to learn more?
(Other definitions for analgesia that I've seen before include "No hard feelings" , "painless" , "As a linage (anag) - insensibility to pain" , "Inability to feel pain" , "Absence of pain" .)
