Fresh title adopted by infernal poet and dabbler (10)
I believe the answer is:
dilettante
'dabbler' is the definition.
(synonyms)
'fresh title adopted by infernal poet' is the wordplay.
'fresh' is an anagram indicator.
'adopted by' indicates putting letters inside (I've seen this in other clues).
'infernal poet' becomes 'Dante' (Dante Alighieri, poet who wrote Inferno).
'title' anagrammed gives 'ilett'.
'ilett' inserted within 'dante' is 'DILETTANTE'.
'and' is the link.
(Other definitions for dilettante that I've seen before include "Aesthete" , "One with superficial knowledge" , "amateur artist" , "Amateur art lover" , "Superficial art lover" .)
