Tragically, ape isn't living (7)
I believe the answer is:
sapient
'living' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I don't see?
'tragically ape isn't' is the wordplay.
'tragically' indicates an anagram (I've seen this in other clues).
'ape'+'isnt'='apeisnt'
'apeisnt' with letters rearranged gives 'SAPIENT'.
Can you help me to learn more?
(Other definitions for sapient that I've seen before include "very keen" , "Acutely insightful and wise" , "Discerning" , "Having intelligence" , "Snipe at, being wise" .)
