Suitable encounter (4)
I believe the answer is:
meet
This clue is a double definition.
'suitable' is the first definition.
(synonyms)
'encounter' is the second definition.
(I know that encounter can be written as meet)
(Other definitions for meet that I've seen before include "Bump into" , "counter" , "See 24" , "Hunt gathering" , "Proper; touch" .)
