When there'll be no more need for longing? (7)
I believe the answer is:
shortly
'when' is the definition.
Both the definition and answer are adverbs. Perhaps you can see an association between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for shortly that I've seen before include "Soon: in an abbreviated manner" , "Soon; sharply" , "In a jiffy" .)
