Chap creating traffic hold up in African city (8)
I believe the answer is:
benjamin
'chap' is the definition.
'traffic hold up in african city' is the wordplay.
'traffic' becomes 'jam' (I have seen 'awful traffic' mean 'jam' so perhaps 'traffic' could also mean 'jam').
'hold' is an insertion indicator.
'up in african city' becomes 'benin' (I can't explain this - if you can you should believe this answer much more).
'jam' put within 'benin' is 'BENJAMIN'.
'creating' acts as a link.
Can you help me to learn more?
(Other definitions for benjamin that I've seen before include "Son of Jacob" , "Jacob's youngest son" , "-- Disraeli; -- Franklin" , "Head of tribe" , "ancient tribe" .)
