Tied up and whipped (6)
I believe the answer is:
lashed
I believe this clue is a double definition.
'tied up' is the first definition.
(I've seen this in another clue)
'whipped' is the second definition.
('lash' can be a synonym of 'whip')
'and' acts as a link.
(Other definitions for lashed that I've seen before include "Hit" , "Fastened securely" , "severely punished" , "Tied -- beaten" , "Flogged" .)
