In Birmingham, a street ahead (5)
I believe the answer is:
aston
'in birmingham' is the definition.
The definition suggests a singular noun which matches the answer.
'a street ahead' is the wordplay.
'street' becomes 'st' (abbreviation).
'ahead' becomes 'on' (synonyms).
'a'+'st'+'on'='ASTON'
Can you help me to learn more?
(Other definitions for aston that I've seen before include "Premiership FC" , "district of Birmingham" , "Area of Birmingham" , "A Birmingham university" , "part of Birmingham" .)
