The word aficionado has appeared in 65 articles on NYTimes.com in the past year, including on Sept. 19 in “Ruth Bader Ginsburg Loved Opera, and Opera Loved Her Back” by Francesca Zambello:
Many prominent people attend the opera occasionally, but Justice Ginsburg was almost an obsessive. She saw her first opera — a condensed version of “La Gioconda” — in 1944, when she was 11, and was immediately hooked, becoming the kind of aficionado who goes to dress rehearsals, and then opening nights, and then closing nights, too, for good measure.
“Most of the time, even when I go to sleep, I’m thinking about legal problems,” she said in 2015. “But when I go to the opera, I’m just lost in it.”
