remarkable
Very unusual or excellent in a way people notice.
Remarkable means worthy of being noticed or talked about because it's unusual, impressive, or exceptional. When something is remarkable, it stands out from the ordinary in a significant way.
A remarkable test score is so outstanding that your teacher mentions it to the class. A remarkable discovery in science changes how people understand the world. When someone shows remarkable courage, they do something brave that people remember and admire.
Not everything deserves a remark. Your breakfast cereal probably isn't remarkable (unless you invented a new flavor). But if you built a working robot for the science fair, or your grandmother survived an incredible adventure, or an athlete broke a record that stood for fifty years, those things are remarkable.
What makes something remarkable varies by context. A six-year-old who plays piano well might be remarkable because it's unusual for that age. A professional pianist would need to do something extraordinary to be called remarkable, since playing well is expected. The word suggests that something has exceeded normal expectations in a memorable way.
