Treat angina in religious Bow man (8)
I believe the answer is:
paganini
'bow man' is the definition.
The definition suggests a singular noun which matches the answer.
'treat angina in religious' is the wordplay.
'treat' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'religious' becomes 'pi' (british abbreviation for pious).
'angina' is an anagram of 'aganin'.
'aganin' placed inside 'pi' is 'PAGANINI'.
Can you help me to learn more?
(Other definitions for paganini that I've seen before include "was often on the fiddle" , "Nineteenth century violin virtuoso" , "C19 violin virtuoso" , "One on the fiddle" , "Violin virtuoso and composer" .)
