Bad as me? No difference! (4)
I believe the answer is:
same
'bad as me? no difference' is the definition.
I can't judge whether this defines the answer.
'bad as me?' is the wordplay.
'bad' indicates anagramming the letters.
'me?' becomes 'me' ().
'as' is an anagram of 'sa'.
'sa'+'me'='SAME'
Can you help me to learn more?
(Other definitions for same that I've seen before include "Identical, not different" , "If - be the food of love, play on (Twelfth Night)" , "Identical, unchanged" , "Identical or similar" , "Ditto" .)
