Related to change, modified (7)
I believe the answer is:
altered
'modified' is the definition.
('altered' can be similar in meaning to 'modified')
'related to change' is the wordplay.
'to change' indicates anagramming the letters.
'related' with letters rearranged gives 'ALTERED'.
(Other definitions for altered that I've seen before include "Different" , "Reformed" , "Change" , "Changed, adapted" , "Converted" .)
