Surviving drug nine properly (8)
I believe the answer is:
enduring
'surviving' is the definition.
('endure' can be a synonym of 'survive')
'drug nine properly' is the wordplay.
'drug nine' can be anagrammed to 'ENDURING'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for enduring that I've seen before include "Putting up with patiently" , "Lasting, unceasing" , "Eternal" , "Long-lasting" , "Going through" .)
