Wait for a friend at the end of the road (5)
I believe the answer is:
dally
'wait' is the definition.
(thesaurus)
'friend at the end of the road' is the wordplay.
'friend' becomes 'ally' (an ally is a friend or supporter).
'at' means one lot of letters go next to another (I've seen this in other clues).
'the end of the' says to take the final letters.
The last letter of 'road' is 'd'.
'ally' put after 'd' is 'DALLY'.
'for a' acts as a link.
(Other definitions for dally that I've seen before include "Dawdle - delay" , "Procrastinate" , "Move slowly" , "Linger" , "Waste time" .)
