Spanish language

Spanish (Spanish: espanol, pronounced "Eh-span-yole", IPA: /espanol/), also called Castilian, is a Romance language. It is the most spoken Romance language in the world. As of December 2021, over 489 million people in the world spoke Spanish as their first language.
Brief history
The Spanish language came from a dialect of spoken Latin. In 218 BC, it was brought to the Iberian Peninsula by the Romans. After evolving and improving for centuries, it is the world's 4th most spoken language today with over 489 million native speakers, after English, Mandarin Chinese, and Hindi.
Usage
Spanish is used by many people in the world today, partly because Spain traveled and colonized many different parts of the world and created many new countries and governments. The countries with Spanish as an official language are called the Hispanic countries. Most of them are in the Americas, which make up Latin America. They include the following:
In North America, Central America, and the Caribbean Islands:
Costa Rica
Cuba
The Dominican Republic
Guatemala
Honduras
Mexico
Nicaragua
Panama
Puerto Rico
El Salvador
In the United States and Belize, most people use English, but Spanish is the second-most common language.
In South America:
Argentina
Bolivia
Chile
Colombia
Ecuador
Guyana
Paraguay
Peru
Uruguay
Venezuela
Many Brazilians learn Spanish as a second language even though Brazil's official language is Portuguese.

Related languages
The Spanish language was originally the language of Castile. When the Western Roman Empire collapsed, Latin changed in different ways in different provinces. The Latin spoken in the Iberian Peninsula developed into the Ibero-Romance language in the 6th century. Castilian and Portuguese became separate languages around the 12th century.
In Spain, there are other languages that also came from Latin that are connected to Spanish, like Catalan, and Galician. Basque, also called Euskera or Euskara, is spoken in the Basque region of northern Spain and the southern region of France. Very different from Spanish, Basque is a language isolate since it is not known to have descended from any language family.
Catalan is not a dialect of Spanish and is actually more closely related to French.
Name
Spanish is sometimes called Castilian because Castile is the region in Spain that is the origin of the language. Castile is the region that is considered to speak the most proper form of Spanish.
The Spanish word for Spanish is "espanol", and the Spanish word for Castilian is "castellano". In the other Romance languages spoken on the Iberian Peninsula, such as Galician, Catalan, Asturian, and others, Spanish is usually called "Castellan" or "Castella" instead of "Spanish". In Spain, the name of the subject in schools is "lengua castellana" (Castilian language). However, in the regions of Spain in which people speak only Spanish, people call their language Spanish.
In Portuguese, the word "castelhano" is common to mention Spanish, however, in informal language, the most preferred name for the language is "espanhol". Portuguese, which is spoken in Portugal and Brazil, has many similarities to Spanish.
