Hot personality turned to carnality (5)
I believe the answer is:
flesh
'carnality' is the definition.
(thesaurus)
'hot personality turned' is the wordplay.
'hot' becomes 'h' (abbreviation eg on taps).
'personality' becomes 'self' (I've seen this before).
'turned' says the letters should be written in reverse.
'h'+'self'='hself'
'hself' reversed gives 'FLESH'.
'to' is the link.
(Other definitions for flesh that I've seen before include "Bodily appetites" , "Soft tissue of animals" , "Soft animal tissue, meat" , "Soft exterior substance of an animal body" , "Body, not spirit" .)
