Badly, wrongly (3)
I believe the answer is:
ill
This clue is a double definition.
'badly' is the first definition.
('ill' can be adverbial as in 'ill-advised')
'wrongly' is the second definition.
(as in ill-advised, ill-gotten etc)
(Other definitions for ill that I've seen before include "Seasick" , "Unwell, sick" , "Wicked" , "In short, the state of Chicago" , "Misfortune" .)
