One tried desperately to have found one's place (8)
I believe the answer is:
oriented
'found one's place' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'one tried desperately' is the wordplay.
'desperately' indicates an anagram.
'one'+'tried'='onetried'
'onetried' anagrammed gives 'ORIENTED'.
'to have' is the link.
Can you help me to learn more?
(Other definitions for oriented that I've seen before include "Made to face in a certain direction - the East? (8)" , "Placed in relation to compass, or accustomed to things" , "Aligned" , "Got bearings or became accustomed to" .)
