Brought a bit of news to the doctor (4)
I believe the answer is:
drew
'brought a bit' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'news to the doctor' is the wordplay.
'news' becomes 'ew' (I can't explain this - if you can you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the doctor' becomes 'Dr' (abbreviation).
'ew' after 'dr' is 'DREW'.
'of' is the link.
Can you help me to learn more?
(Other definitions for drew that I've seen before include "took in" , "Made lines on a surface" , "Sketched; attracted" , "Sketched or tied in a game" , "Pictured" .)
