If you have qobuz, many times the libretto is available with the album and Roon can show it. Also I believe that the Metropolitan opera are doing free streams in these times, but you could also buy a week or a months subscription and watch at your leisure with subtitles. Which reminds me, there is a famous Jonathon Miller production of The Marriage of Figaro that I have never seen which is available from the Met, so I shall watch that this week.
As an update, we have found that my wife definitely DOESN’T like opera. Despite liking music sung with overblown histrionics in a foreign language. (Greek pop songs)
She likes some arias but not the whole thing.
