Nat King Cole song that will always be remembered? (13)
I believe the answer is:
unforgettable
'remembered?' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for unforgettable that I've seen before include "Always remaining in the mind" , "Striking" , "Highly memorable" , "Nat King Cole's memorable song?" , "stuck in my brain?" .)
