You alone find it (8)
I believe the answer is:
solitude
'it' is the definition.
The definition suggests a singular noun which matches the answer.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for solitude that I've seen before include "Lone state" , "Seclusion" , "State of aloneness" , "State of being alone without companions" , "Avoiding company" .)
