Hard-nosed type that might charge you (5)
I believe the answer is:
rhino
'you' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rhino that I've seen before include "Animal hunted for its horn" , "In brief, large thick-skinned animal of Africa" , "Large African pachyderm" , "Ready" , "Horned animal; money (slang)" .)
