Personal cleanliness (7)
I believe the answer is:
hygiene
'personal cleanliness' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hygiene that I've seen before include "Cleanliness, sanitation" , "Clean and healthy practices" , "Clean, healthy habits" , "Practice of cleanliness to maintain health" , "Healthy cleanliness" .)
