eminent
Very important and highly respected in a certain field.
Eminent means highly respected and distinguished in a particular field. An eminent scientist has made important discoveries that other scientists admire and build upon. An eminent judge has years of experience and a reputation for wisdom and fairness. When someone is described as eminent, they've reached the top of their profession through skill, knowledge, and achievement.
The word suggests exceptional standing recognized by peers in the field. An eminent doctor is recognized by other medical professionals as exceptional in diagnosis, treatment, or research. An eminent historian has written books and conducted research that have shaped how others understand the past.
You'll often see this word in formal contexts: “We invited an eminent mathematician to speak at our school” or “The museum consulted with eminent experts before the exhibit.” The word carries respect and formality. You wouldn't typically call your friend who's great at soccer eminent, even if she's the best player on the team. But if she became a legendary coach whose methods changed how the sport is taught, then eminent would fit.
People sometimes confuse eminent with imminent (meaning about to happen), but they're completely different words. Remember: eminent people stand out in their field.
