Computerised assistance used by parent to write opera (4)
I believe the answer is:
aida
'opera' is the definition.
(Verdi opera)
'computerised assistance used by parent to' is the wordplay.
I cannot quite understand how this works, but
'assistance' could be 'aid' (synonyms) and 'aid' is found in the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'write' acts as a link.
Can you help me to learn more?
(Other definitions for aida that I've seen before include "work of grand proportions" , "Operatic lady" , "Princess" , "slave of Covent Garden" , "Verdi's slave girl" .)
