Assumed choice of directions (4)
I believe the answer is:
worn
'assumed choice of directions' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe there's a link between them I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for worn that I've seen before include "Frayed" , "Looking tired and exhausted" , "Shabby" , "Damaged by long use" , "Hackneyed, trite" .)
