They're in the archives as edible (6)
I believe the answer is:
chives
'edible' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'they're in the archives as' is the wordplay.
'CHIVES' is hidden in amongst the letters.
But, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for chives that I've seen before include "Plants" , "Herb of the onion family" , "Herbs with long tubular onionflavoured leaves" , "Plant of onion family" , "Leaves used as onion-flavoured seasoning" .)
