Criticise returned pastry items. Some are disposable (7)
I believe the answer is:
nappies
'items some are disposable' is the definition.
I can't tell whether this defines the answer.
'criticise returned pastry' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'returned' shows that the letters should be reversed in order.
'pastry' becomes 'pies' (I've seen this in another clue).
'pan' reversed gives 'nap'.
'nap'+'pies'='NAPPIES'
Can you help me to learn more?
(Other definitions for nappies that I've seen before include "Baby's pads" , "Cloths for babies" , "What Americans call diapers" , "They keep babies dry" , "They're diapers in America" .)
