Bakery product consumed by a short Italian poet is more than enough (8)
I believe the answer is:
abundant
'more than enough' is the definition.
(I've seen this before)
'bakery product consumed by a short italian poet' is the wordplay.
'bakery product' becomes 'bun'.
'consumed by' is an insertion indicator (inserted letters get consumed).
'short' means to remove the last letter.
'italian poet' becomes 'Dante' (Dante Alighieri).
'dante' with its last letter taken away is 'dant'.
'a'+'dant'='adant'
'bun' placed inside 'adant' is 'ABUNDANT'.
'is' is the link.
(Other definitions for abundant that I've seen before include "Copious, profuse" , "Plentiful, more than enough" , "Existing in large amounts" , "Bountiful" , "full" .)
