Many a complaint has a culinary connection (6)
I believe the answer is:
chives
'a culinary connection' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'many a complaint' is the wordplay.
'many a' becomes 'c' (I can't justify this - if you can you should believe this answer much more).
'complaint' becomes 'hives' (I've seen this before).
'c'+'hives'='CHIVES'
'has' is the link.
Can you help me to learn more?
(Other definitions for chives that I've seen before include "Herb of the onion family" , "Plants" , "Plant of onion family" , "Herbs with long tubular onionflavoured leaves" , "Leaves used as onion-flavoured seasoning" .)
