Articulated large scale arch provides passage in Venice (6,2,5)
I believe the answer is:
bridge of sighs
'passage in venice' is the definition.
The definition suggests a singular noun which matches the answer.
'articulated large scale arch' is the wordplay.
I cannot quite see how this works, but
'arch' could be 'bridge' (both can mean a curve) and 'bridge' is located in the answer.
The remaining letters 'ofsighs' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'provides' acts as a link.
Can you help me to learn more?
(Other definitions for bridge of sighs that I've seen before include "Venetian landmark" , "Venetian construction across which prisoners were once led to trial" , "feature of Venice" , "Prison passage" , "Structure in Venice" .)
