Remarkable – individual (8)
I believe the answer is:
singular
This could be a double definition.
'remarkable' is the first definition.
(I know that remarkable can be written as singular)
'individual' is the second definition.
Both the answer and definition are adjectives. Perhaps you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for singular that I've seen before include "Remarkable - unique" , "Denoting one" , "Odd; unique" , "Remarkable; not plural" , "Extraordinary - just one (8)" .)
