Bounce back although tied up again (7)
I believe the answer is:
rebound
I believe this is a double definition.
'bounce back' is the first definition.
(I've seen this before)
'tied up again' is the second definition.
('bound' can be a synonym for 'tied up' so perhaps 'rebound' is OK for 'tied up again')
'although' acts as a link.
(Other definitions for rebound that I've seen before include "tied again?" , "recover" , "misfire" , "Spring back on impact" , "Spring back, bounce" .)
