Something that rises possibly ends care (8)
I believe the answer is:
ascender
'something that rises' is the definition.
I can't tell whether this definition defines the answer.
'possibly ends care' is the wordplay.
'possibly' is an anagram indicator.
'ends'+'care'='endscare'
'endscare' anagrammed gives 'ASCENDER'.
Can you help me to learn more?
(Other definitions for ascender that I've seen before include "Top part of lower-case letter such as b or d" , "What goes up" , "Top part of a tall lower-case letter" , "One climbing" , "Climber" .)
