Stop over is where you arrive eventually (3,2)
I believe the answer is:
end up
'arrive eventually' is the definition.
(I've seen this before)
'stop over is where' is the wordplay.
I cannot really understand how this works, but
'stop' could be 'end' (synonyms) and 'end' is found in the answer.
'over' could be 'up' (e.g. if your time is up it is over) and 'up' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'you' acts as a link.
Can you help me to learn more?
(Other definitions for end up that I've seen before include "Arrive (after long process)" , "standing on one's head" , "Arrive eventually" , "inverted" , "Arrive (at); finish (with)" .)
