Florentine poet embracing one Latvian dabbler (10)
I believe the answer is:
dilettante
'dabbler' is the definition.
(synonyms)
'florentine poet embracing one latvian' is the wordplay.
'florentine poet' becomes 'Dante' (Dante Alighieri, poet from Florence).
'embracing' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'latvian' becomes 'Lett' (I've seen this in another clue).
'i'+'lett'='ilett'
'dante' placed around 'ilett' is 'DILETTANTE'.
(Other definitions for dilettante that I've seen before include "One dabbling" , "Superficial dabbler in the arts - title at end (anag)" , "Amateur art lover" , "amateur artist" , "whose study is superficial?" .)
