Moral degeneration rooted in one's person (5)
I believe the answer is:
molar
'one's person' is the definition.
The definition and answer can be both body parts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'moral degeneration rooted' is the wordplay.
'moral' anagrams to 'MOLAR'.
However, I am not clear how this is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for molar that I've seen before include "Large tooth" , "that could be capped" , "Moral (anag.)" , "Grinding tooth in the back of a mammal's mouth" , "Type of tooth" .)
