Selection includes cold confectionery (4,3)
I believe the answer is:
choc ice
'confectionery' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'selection includes cold' is the wordplay.
'selection' becomes 'choice' (synonyms).
'includes' indicates putting letters inside.
'cold' becomes 'c' (eg on taps).
'choice' going around 'c' is 'CHOC-ICE'.
Can you help me to learn more?
(Other definitions for choc ice that I've seen before include "Something to eat" , "dessert" , "Frozen item" , "Cold, coated confection" , "cold snack" .)
