Reap new healthy snack (4)
I believe the answer is:
pear
'healthy snack' 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?
'reap new' is the wordplay.
'new' is an anagram indicator.
'reap' anagrammed gives 'PEAR'.
Can you help me to learn more?
(Other definitions for pear that I've seen before include "Avocado" , "Fruit; sounds like duo" , "Brand" , "Shapely fruit?" , "Source of cider" .)
