Quotes
Lady Dalton was not her usual, cheery self, as she kissed and handed us down the line, and while all the usual forms were observed -- the ancient village church, the marquee on the lawn, the plates of unappetising nibbles, the rather good champagne -- none of it seemed to be celebrated with much brio.
-- Julian Fellowes, "Past Imperfect," 2008
Origin
Brio entered English most directly from Italian in the early 1700s. Ultimately it derives from the Celtic word brīgos, which means "strength."
