Edward I, meeting another Edward, getting changed (6)
I believe the answer is:
edited
'changed' is the definition.
(editing is a kind of changing)
'edward i meeting another edward' is the wordplay.
'edward' becomes 'Ed' (short for Edward).
'meeting' says to put letters next to each other.
'another edward' becomes 'ted' (I am not sure about the 'another' bit.).
'ed'+'i'+'ted'='EDITED'
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for edited that I've seen before include "Prepared a paper" , "altered for publication" , "Amended" , "Revised" , "Prepared text for publication" .)
