A concert hall in the street (6)
I believe the answer is:
avenue
'the street' is the definition.
(avenue is a kind of street)
'a concert hall' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
The remaining letters 'venue' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for avenue that I've seen before include "A wide street or access route" , "Tee-lined road" , "Wide, straight road" , "Means of approach" , "A line of approach" .)
