Some pundit told the same thing (5)
I believe the answer is:
ditto
'the same thing' is the definition.
(the thing previously mentioned in a list)
'some pundit told' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'DITTO' is hidden within 'pundit told'.
(Other definitions for ditto that I've seen before include "Likewise" , "couple of marks" , "Two small marks indicating the same again" , "Notation meaning the same again" , "Copy" .)
