Uncompromising, like a rhinoceros? (4-5)
I believe the answer is:
hard-nosed
'uncompromising' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for hard-nosed that I've seen before include "Realistic and tough-minded" , "Unsentimental, shrewd" , "Tough and uncompromising" .)
