Stopping briefly, not answering, finished (7,7)
I believe the answer is:
passing through
'stopping briefly not' is the definition.
I can't tell whether this defines the answer.
'answering finished' is the wordplay.
'answering' becomes 'passing' (I can't explain this - if you can you should give a lot more credence to this answer).
'finished' becomes 'through' (similar in meaning).
'passing'+'through'='PASSING THROUGH'
Can you help me to learn more?
(Another definition for passing through that I've seen is " Via".)
