Darling, switch pans for a vegetable (5,4)
I believe the answer is:
sugar snap
'a vegetable' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'darling switch pans' is the wordplay.
'darling' becomes 'sugar' (I've seen this in another clue).
'switch' shows that the letters should be reversed in order (I've seen 'switching' mean this (switching direction)).
'pans' reversed gives 'snap'.
'sugar'+'snap'='SUGAR SNAP'
'for' is the link.
Can you help me to learn more?
(Other definitions for sugar snap that I've seen before include "Vegetable's" , "Mangetout" , "item of food" .)
