International organisation to protect old city: way one can make people feel better? (10)
I believe the answer is:
naturopath
'one can make people feel better?' is the definition.
(a naturopath treats people with natural remedies)
'international organisation to protect old city way' is the wordplay.
'international organisation' becomes 'NATO' (North Atlantic Treaty Organisation).
'to protect' indicates putting letters inside.
'old city' becomes 'ur' (ancient city state).
'way' becomes 'path' (path is a kind of way).
'nato' going around 'ur' is 'naturo'.
'naturo'+'path'='NATUROPATH'
(Other definitions for naturopath that I've seen before include "Healer" , "Alternative medicine practitioner" .)
