Italian opera house showing a range not fully achieved in US city (2,5)
I believe the answer is:
la scala
'italian opera house' is the definition.
(I've seen this before)
'a range not fully achieved in us city' is the wordplay.
I cannot quite see how this works, but
'a' is within the answer.
'city' could be 'la' (Los Angeles) and 'la' is present in the answer.
This explanation may well be incorrect...
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for la scala that I've seen before include "music centre" , "A Callas may find way to Milan's famous opera house" , "noted venue?" , "place to sing" , "A Callas seen in famous Milan opera house" .)
