Wait for a friend at the end of the road (5)
I believe the answer is:
dally
'wait' is the definition.
(thesaurus)
'a friend at the end of the road' is the wordplay.
'a friend' becomes 'ally' ('ally' can be a synonym of 'friend').
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the end of' indicates one should take the final letters.
The last letter of 'road' is 'd'.
'ally' put after 'd' is 'DALLY'.
'for' is the link.
(Other definitions for dally that I've seen before include "Dawdle - delay" , "Procrastinate" , "Move slowly" , "Linger" , "Waste time" .)
