Approach and confront (6)
I believe the answer is:
accost
'approach and confront' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for accost that I've seen before include "Approach, stop and speak to" , "Nobble" , "such as a solicitor might do" , "Come up and address" , "Approach boldly and speak to" .)
