Unlike chalk and cheese (4)
I believe the answer is:

'unlike' is the first definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I can't see?
'chalk and cheese' is the second definition.
Both the definition and answer are adjectives.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for same that I've seen before include "uniform" , "Equal in amount or value" , "Identical or similar" , "Aforesaid" , "Identical, unchanged" .)
