Is able to divide into sections as French or Italian ballad (7)
I believe the answer is:
canzone
'ballad' is the definition.
(I know that canzone is a type of ballad)
'is able to divide' is the wordplay.
'is able to' becomes 'can' (if you can do something you are able to do it).
'divide' becomes 'zone' (zoning is a kind of dividing).
'can'+'zone'='CANZONE'
'into sections as french or italian' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for canzone that I've seen before include "lyric poetry?" , "Ballad from Italy" , "song?" .)
