Goes by (6)
I believe the answer is:
passes
'goes by' is the definition.
('pass' can be a synonym of 'go by')
This is the entire clue.
(Other definitions for passes that I've seen before include "Documents indicating permission" , "Time always does it" , "Moves like mountain gaps" , "'Men seldom make . . . at girls who wear glasses'" , "Achieves the required standard in a test" .)
