Article on apt cure I adapted for healing (11)
I believe the answer is:
therapeutic
'healing' is the definition.
('therapeutic' can be a synonym of 'healing')
'article on apt cure i adapted' is the wordplay.
'article' becomes 'the' (the 'definite article' part of speech**).
'on' says to put letters next to each other.
'adapted' is an anagram indicator.
'apt'+'cure'+'i'='aptcurei'
'aptcurei' anagrammed gives 'rapeutic'.
'the'+'rapeutic'='THERAPEUTIC'
'for' acts as a link.
(Other definitions for therapeutic that I've seen before include "of healthy properties" , "Relating to the healing of disease" , "Remedial" , "Helping to cure" , "Curative" .)
