IPA: /ˈzɛnɪθ/
KK: /ˈzinəth/
The highest point or peak of something, often used to describe a person's career or a celestial body in the sky.
After years of hard work, she finally reached the zenith of her career as a director.
Zenith comes from the Arabic 'samt' (meaning direction or path) and the Latin 'zenith' (meaning the highest point). The word describes the highest point reached by a celestial object in the sky, particularly the sun or stars.
Imagine the highest point in the sky where the sun shines directly above — that's what zenith means.
