Pass by poor region (6)
I believe the answer is:
ignore
'pass by' is the definition.
(I've seen this before)
'poor region' is the wordplay.
'poor' indicates an anagram.
'region' anagrammed gives 'IGNORE'.
(Other definitions for ignore that I've seen before include "Pay no attention to, disdain" , "Deliberately disregard" , "Turn a blind eye to" , "Disregard - cut" , "Fail to notice (6)" .)
