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 you can see an association between them that I don't see?
'perhaps' is the second definition.
Both the definition and answer are adverbs. Perhaps there's a link between them I don't understand?
'over' is the 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" .)
