Side-by-side comparison
Earth
noun"Earth" refers to the physical planet, the ground, or soil as a natural element. Capitalized, it is the proper name of the planet.

Common mistake
- •"She is the best in the earth" is not natural in English: use "world" for human comparisons, achievements, and fields of activity.
- •"Earth" is for the physical planet, geology, or soil.
Trick to remember it
- •"Earth" = science, geology, nature ("the center of the Earth", "earthquake").
- •"World" = people, comparisons, human achievements ("the best in the world", "travel the world", "the business world").
Quick rule
- •"Earth" = the physical planet or soil.
- •"World" = humanity or a field of activity.
Did you know?
"Earthly" and "worldly" perfectly reflect the difference: "earthly pleasures" (physical, of the ground) and "worldly experience" (of the human world and its affairs). "Earthquake" uses "earth" because it is a physical planetary phenomenon. "World record" uses "world" because it is a human achievement measured among people. The distinction is so embedded in English that swapping them sounds immediately wrong to native ears.
