Recognised to end in chaos (5)
I believe the answer is:
noted
'recognised to end in chaos' is the definition.
I can't judge whether this definition defines the answer.
'to end in chaos' is the wordplay.
'in chaos' indicates an anagram.
'to'+'end'='toend'
'toend' with letters rearranged gives 'NOTED'.
Can you help me to learn more?
(Other definitions for noted that I've seen before include "Toned down and recorded" , "remarked upon" , "Famous or eminent" , "written down" , "Gaiter; oyster spawn" .)
