Wanders drunkenly over to the bus terminus (5)
I believe the answer is:
roves
'wanders' is the definition.
('rove' can be a synonym of 'wander')
'drunkenly over to the bus terminus' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'over' is 'rove' which is present in the answer.
A single letter 's' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for roves that I've seen before include "Wanders far and wide" , "Travels about, hits the road (5)" .)
