Aria in opera house ultimately captured by boy on phone (2,5,1,6)
I believe the answer is:
la donna e mobile
'aria in opera house ultimately captured' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'boy on phone' is the wordplay.
I cannot really understand how this works, but
'boy' could be 'donn' and 'donn' is found within the answer.
'phone' could be 'mobile' (mobile phone) and 'mobile' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for la donna e mobile that I've seen before include "song" , "Theme of inconstancy" , "number" , "Woman so fickle" , "operatic piece" .)
