Pail on Etna tickled Italian living near volcano (10)
I believe the answer is:
neapolitan
'pail on etna tickled italian living near volcano' is the definition.
I can't tell whether this definition defines the answer.
'pail on etna tickled' is the wordplay.
'tickled' indicates anagramming the letters (letters tickled out of place).
'pail'+'on'+'etna'='pailonetna'
'pailonetna' with letters rearranged gives 'NEAPOLITAN'.
Can you help me to learn more?
(Other definitions for neapolitan that I've seen before include "Italian native" , "Italian citizen" , "21 [ITALIAN]" , "Three-coloured ice cream" , "From Naples" .)
