Traffic hold-up near Cork? (10)
I believe the answer is:
bottleneck
'traffic hold-up' is the definition.
'bottleneck' can be an answer for 'hold-up' (I've seen this before). I am unsure of the 'traffic' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bottleneck that I've seen before include "Where traffic is squeezed" , "Congestion" , "Liquid is poured through it" , "Where one may get trapped" , "Constricted section of road" .)
