Rapid rise can turn into collapse (9)
I believe the answer is:
disrepair
'collapse' is the definition.
(thesaurus)
'rapid rise can turn into' is the wordplay.
'can turn into' indicates anagramming the letters.
'rapid'+'rise'='rapidrise'
'rapidrise' with letters rearranged gives 'DISREPAIR'.
(Other definitions for disrepair that I've seen before include "Neglected condition" , "rack and ruin" , "Poor working order" , "Degradation" , "Poor condition" .)
