Is inclined to delete nothing from pieces of poetry (5)

'is inclined' is the definition.
(cant can mean to tilt or incline)

'nothing from pieces of poetry' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'from' suggests deleting specific letters.
'pieces of poetry' becomes 'cantos' (a canto is a section of a long poem).
'cantos' with 'o' taken away is 'CANTS'.

'to delete' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
