Pass over; disregard (6)
I believe the answer is:
ignore
This clue is a double definition.
'pass over' is the first definition.
(I've seen this before)
'disregard' is the second definition.
(I know that disregard can be written as ignore)
(Other definitions for ignore that I've seen before include "Deliberately overlook" , "Spurn" , "Turn a blind eye to" , "Dismiss" , "Fail to observe" .)
