Insist on editor returning to meet person with delicious lead (6)
I believe the answer is:
demand
'insist on' is the definition.
(I've seen this before)
'editor returning to meet person with delicious lead' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'returning' says the letters should be written backwards.
'to meet person with' becomes 'man' (I am not sure about this - if you are sure you should believe this answer much more).
'lead' indicates taking the first letters.
The initial letter of 'delicious' is 'd'.
'ed' in reverse letter order is 'de'.
'de'+'man'+'d'='DEMAND'
Can you help me to learn more?
(Other definitions for demand that I've seen before include "Request urgently" , "Request forcefully" , "Madden (anag)" , "Ask peremptorily or call for" , "An imperious request made as if by right" .)
