Made personal changes to MBE (nothing added) and departed (8)
I believe the answer is:
embodied
'made personal' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.
'changes to mbe nothing added and departed' is the wordplay.
'changes to' indicates an anagram (I've seen 'change to' mean this).
'nothing' becomes 'O' (O resembles 0).
'added' is a charade indicator (letters next to each other).
'and' means one lot of letters go next to another.
'departed' becomes 'died' (I can't explain this - if you can you should believe this answer much more).
'mbe' with letters rearranged gives 'emb'.
'emb'+'o'+'died'='EMBODIED'
Can you help me to learn more?
(Other definitions for embodied that I've seen before include "Incorporated" , "Expressed" .)
