Italian maestro botched a painting without model (8)
I believe the answer is:
paganini
'italian maestro' is the definition.
The definition suggests a singular noun which matches the answer.
'botched a painting without model' is the wordplay.
'botched' indicates an anagram.
'without' indicates named letters should be taken away.
'model' becomes 't' (Ford Model T car).
'a'+'painting'='apainting'
'apainting' with 't' removed is 'apaining'.
'apaining' with letters rearranged gives 'PAGANINI'.
Can you help me to learn more?
(Other definitions for paganini that I've seen before include "was often on the fiddle" , "who was always on the fiddle" , "Famous violin virtuoso" , "Niccolo --, Italian violinist" , "One on the fiddle" .)
