Show resilience when tied up again (7)
I believe the answer is:
rebound
This clue could be a double definition.
'show resilience' is the first definition.
'rebound' can be an answer for 'resilience' (thesaurus). I'm not certain of the 'show' bit.
'tied up again' is the second definition.
('bound' can be a synonym for 'tied up' so perhaps 'rebound' is OK for 'tied up again')
'when' acts as a link.
Can you help me to learn more?
(Other definitions for rebound that I've seen before include "tied again?" , "Deflection" , "Ricochet" , "Spring back, bounce" , "Spring back on impact" .)
