Spoken greeting to woman providing sanitation? (7)

I believe the answer is:

hygiene

'sanitation?' is the definition.
(thesaurus)

I don't understand the remainder of the clue.

(Other definitions for hygiene that I've seen before include "Clean, healthy habits" , "Personal cleanliness" , "Sanitary practices conducive to health" , "The practice or conditions of cleanliness" , "The practice of cleanliness for health reasons" .)

I've seen this clue in The Times and The Sun.
