Dim foe I'd routed changed (8)
I believe the answer is:
modified
'changed' is the definition.
(I know that changed can be written as modified)
'dim foe i'd routed' is the wordplay.
'routed' indicates anagramming the letters.
'dim'+'foe'+'id'='dimfoeid'
'dimfoeid' is an anagram of 'MODIFIED'.
(Other definitions for modified that I've seen before include "Changed slightly, form or quality" , "tweaked" , "Made minor changes to" , "Altered, changed" , "Reformed" .)
