Aunts chew strange snack item (6,3)
I believe the answer is:
cashew nut
'snack item' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's a link between them I don't understand?
'aunts chew strange' is the wordplay.
'strange' indicates an anagram.
'aunts'+'chew'='auntschew'
'auntschew' is an anagram of 'CASHEW NUT'.
Can you help me to learn more?
(Other definitions for cashew nut that I've seen before include "Rich source of oil and protein" , "Product of tree" , "Edible fruit of American tree" , "Kidney-shaped snack" .)
