Called for northern adult section to disappear (6)
I believe the answer is:
needed
'called for' is the definition.
('need' can be a synonym of 'call for')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for needed that I've seen before include "Essential; called for" , "Required; sounds like worked (dough)" , "'Lacked, required (6)'" , "Obligatory" , "'Wanted, required (6)'" .)
