Came together (3)
I believe the answer is:
met
'came together' is the definition.
(meeting is a kind of coming together)
This is the entire clue.
(Other definitions for met that I've seen before include "Bumped into" , "London police (abbr) - New York Museum of Art (abbr)" , "Encountered or touched" , "Came across - police in London" , "Came together, encountered" .)
