Vindicated one against English edition (7)
I believe the answer is:
avenged
'vindicated' is the definition.
(I've seen this in another clue)
'one against english edition' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'against' becomes 'v' (versus).
'english' becomes 'eng' (abbreviation).
'edition' becomes 'ed'.
'a'+'v'+'eng'+'ed'='AVENGED'
(Other definitions for avenged that I've seen before include "Got back at" , "Inflicted retribution for (a wrong)" , "Took reprisals for" , "being paid back" .)
