Make a spring comeback (6)
I believe the answer is:
bounce
'spring comeback' is the definition.
'bounce' can be an answer for 'spring' (synonyms). I am not sure about the 'comeback' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bounce that I've seen before include "Springiness" , "Reflect back from a surface" , "What a cheque may do if there are insufficient funds" , "Hop like rubber ball" , "Move energetically; rebound" .)
