The world is the earth and all the people, places, and things on it. It can also refer to a particular area of activity or experience, such as the world of business or the natural world.
What Does World Mean?
World is one of the most frequently used nouns in English. Its primary meaning is the planet Earth considered as a whole, together with its human inhabitants and natural features. When someone says "English is spoken all over the world", they mean it is used across every country and continent.
Beyond this geographical sense, world is also used to describe a particular sphere or domain of human activity. "The world of fashion", "the business world", and "the academic world" all refer to specific communities and the values, practices, and people within them. This figurative use is extremely common in formal and journalistic English.
A third use is philosophical or emotional — referring to the sum of a person's experience: "She was his whole world." Understanding all three senses will help you read and use this word confidently at any level.

Usage Notes
World is almost always used with the definite article the when it refers to the earth as a whole: "the world", "all over the world", "the world's population". The article is dropped in compound nouns and attributive adjective uses: "world peace", "world trade", "world history", "a world record".
When used figuratively to describe a domain, world takes the definite article and is followed by of: "the world of politics", "the world of finance". This structure is typical in journalism and formal writing.
Be careful with the preposition: we say all over the world or around the world (not in all the world) when describing geographical spread. The phrase in the world is used in superlatives: "the best teacher in the world".
Etymology
World comes from the Old English woruld, which meant "human existence" or "age of man". The word is made up of two Germanic roots: wer (meaning "man", also found in werewolf) and ald (meaning "age"). So the original meaning was literally "the age of man". The word has been in continuous use in English since before the Norman Conquest of 1066, making it one of the oldest and most stable words in the language.
