Went one better than divorcee from old community retiring to Germany on Dutch border (8)
I believe the answer is:
exceeded
'went one better than' is the definition.
'divorcee from old community retiring to germany on dutch border' is the wordplay.
'divorcee' becomes 'ex' (I've seen this in other clues).
'from' means one lot of letters go next to another.
'old community' becomes 'eec' (predecessor to the EU).
'retiring' says the letters should be written in reverse.
'to germany on dutch border' becomes 'ded' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'eec' back-to-front is 'cee'.
'ex'+'cee'+'ded'='EXCEEDED'
Can you help me to learn more?
(Other definitions for exceeded that I've seen before include "went over the top!" , "Went beyond (a limit)" , "Surpassed" , "Went beyond what was required" .)
