Oil making it curable, somehow (9)
I believe the answer is:
lubricate
'oil' is the definition.
(oil can mean to lubricate with oil)
'it curable somehow' is the wordplay.
'somehow' indicates anagramming the letters.
'it'+'curable'='itcurable'
'itcurable' with letters rearranged gives 'LUBRICATE'.
'making' acts as a link.
(Other definitions for lubricate that I've seen before include "Apply oil or grease to" , "Bribe" , "Oil (a mechanism)" , "Apply oil/grease" , "Coat with oil to reduce friction" .)
