renowned
Famous and greatly respected for being very good at something.
Renowned means famous and respected for excellence or achievement. When someone is renowned, they're widely known and admired for being exceptionally good at something. A renowned scientist has made important discoveries that other scientists respect. A renowned chef creates extraordinary food that draws people from miles away.
The word carries a sense of an earned reputation built over time. Someone becomes renowned through consistent excellence, not from a single lucky moment. Marie Curie became renowned for her groundbreaking research on radioactivity. Shakespeare became renowned for writing plays that moved audiences for centuries.
You might read about a renowned expert being called to solve a difficult problem, or a renowned musician performing at a special concert. The word suggests that the person's reputation has spread far beyond their immediate circle. A teacher might be excellent and loved by her students, but a renowned educator influences teaching methods across the country.
