I believe the answer is:

meet

I'm a little stuck... Click here to teach me more about this clue!

'encounter' is the definition.
('meet' can be a synonym of 'encounter')

I don't understand the remainder of the clue.

(Other definitions for meet that I've seen before include "sporting occasion" , "assembly at hunt" , "Come face to face with - it is proper" , "Hunting gathering" , "Join" .)

I've seen this clue in the Evening Standard.
