Fail to answer question — but go through? (4)
I believe the answer is:
pass
This could be a double definition.
'fail to answer' is the first definition.
(I've seen this before)
'question but go through?' is the second definition.
I know that 'go' relates to this answer.
Can you help me to learn more?
(Other definitions for pass that I've seen before include "Narrow route through high mountain, like the Khyber" , "I've no idea" , "degree?" , "Blow over" , "Elapse; mountain route" .)
