Passed over, perhaps (5)
I believe the answer is:
given
This could be a double definition.
'passed' is the first 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?
'perhaps' is the second definition.
Both the answer and definition are adverbs. Maybe there's an association between them I don't understand?
'over' acts as a link.
Can you help me to learn more?
(Other definitions for given that I've seen before include "Known fact" , "Provided" , "Specified, stated" , "Accepted as true" , "Taken as read" .)
