80s singer determined (7)
I believe the answer is:
adamant
This might be a double definition.
'80s singer' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'determined' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for adamant that I've seen before include "Resolute, refusing to yield" , "uncompromising" , "Obdurate and unyielding" , "Resolute; diamond (arch.)" , "popstar" .)
