Joined college with Edward (6)
I believe the answer is:
united
'joined' is the definition.
(I've seen this before)
'college with edward' is the wordplay.
'college' becomes 'uni' (I've seen this in other clues).
'with' means one lot of letters go next to another.
'edward' becomes 'ted'.
'uni'+'ted'='UNITED'
(Other definitions for united that I've seen before include "joined with others" , "Football team" , "Affiliated" , "Whole" , "Agreed" .)
