Spanish refers to things related to Spain, a country in southwestern Europe, or to the language spoken there and in many other parts of the world.

The Spanish language is one of the most widely spoken languages on Earth, with over 500 million speakers. It's the primary language in Spain and in most countries of Central and South America, including Mexico, Argentina, Colombia, and Peru. In the United States, Spanish is the second most common language after English, spoken by millions of families.

Spanish developed from Latin, the language of ancient Rome, after Roman armies conquered the region nearly 2,000 years ago. Over centuries, it evolved into its own distinct language. When Spanish explorers traveled to the Americas in the late 1400s and 1500s, they brought their language with them, which is why Spanish is now spoken across such a vast area of the world.

Learning Spanish opens doors to understanding the literature, music, history, and cultures of dozens of countries. Many English words come from Spanish, like rodeo, canyon, tornado, and mosquito. If you study Spanish, you'll find it shares similarities with other Romance languages like French, Italian, and Portuguese, since they all descended from Latin.

When someone says they're Spanish, they usually mean they're from Spain specifically. People from Spanish-speaking countries in the Americas are typically called by their country's name (Mexican, Argentine, Colombian) or the broader term Hispanic or Latino.
