Altered, adapted (8)
I believe the answer is:
adjusted
This clue is a double definition.
'altered' is the first definition.
(I've seen this before)
'adapted' is the second definition.
('adjust' can be a synonym of 'adapt')
(Other definitions for adjusted that I've seen before include "Altered slightly or regulated" , "With small change" , "Changed to better fit" , "Altered slighty for accuracy" , "Modified" .)
