Animal whose horn is broken just about in half! (5)
I believe the answer is:
rhino
'animal' is the definition.
(short for rhinoceros)
'horn is broken just about in half' is the wordplay.
I cannot quite understand how this works, but
'in' is present in the answer.
The remaining letters 'rho' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'whose' acts as a link.
Can you help me to learn more?
(Other definitions for rhino that I've seen before include "Horned animal; money (slang)" , "one still charges in Africa" , "Large African pachyderm" , "one might charge in Africa" , "In brief, large thick-skinned animal of Africa" .)
