Amateurish poet accepting fancy title (10)
I believe the answer is:
dilettante
'amateurish' is the definition.
(I've seen this before)
'poet accepting fancy title' is the wordplay.
'poet' becomes 'dante' (Dante is an example).
'accepting' indicates putting letters inside.
'fancy' indicates an anagram.
'title' with letters rearranged gives 'ilett'.
'dante' enclosing 'ilett' is 'DILETTANTE'.
(Other definitions for dilettante that I've seen before include "Superficial dabbler in the arts - title at end (anag)" , "Superficial art-lover" , "whose study is superficial?" , "Superficial art lover" , "amateur artist" .)
