Definition of the word brilliant

The word "brilliant" has its roots in the ancient Latin word "brillare," which means "to glitter" or "to shine." This Latin word is a derivative of the word "bril," which refers to a spark or a gemstone. In the 15th century, the word "brilliant" was borrowed into Middle English from Old French, and initially it referred to something that shines or sparkles, such as a diamond. Over time, the meaning of "brilliant" expanded to describe something that is exceptionally good or outstanding, such as a brilliant idea or a brilliant performance. Today, the word "brilliant" is widely used to praise something or someone that is exceptional, impressive, or outstanding.
