Dot it as aforementioned (5)
I believe the answer is:
ditto
'as aforementioned' is the definition.
I can't tell whether this defines the answer.
'dot it' is the wordplay.
'dot it' can be anagrammed to 'DITTO'.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for ditto that I've seen before include "Dot it for the same again" , "In lists, the same again with two small marks" , "Mark used to indicate repetition" , "that which has been said" , "Two dots say same again" .)
