Own a new salon (8)
I believe the answer is:
personal
'own' is the definition.
(similar in meaning)
'a new salon' is the wordplay.
'a' becomes 'per' (eg 'one a day' means 'one per day').
'new' is an anagram indicator.
'salon' is an anagram of 'sonal'.
'per'+'sonal'='PERSONAL'
(Other definitions for personal that I've seen before include "Of private concern" , "Affecting an individual" , "Applied to a particular individual" , "Concerning private life" , "Pertaining to oneself" .)
