Spanish is a Romance language of the Indo-European language family that evolved from colloquial Latin spoken on the Iberian Peninsula. Today, it is a global language with more than 500 million native speakers, mainly in the Americas and Spain. Spanish is the official language of 20 countries. It is the world's second-most spoken native language after Mandarin Chinese; the world's fourth-most spoken language overall after English, Mandarin Chinese, and Hindustani (Hindi-Urdu); and the world's most widely spoken Romance language. The largest population of native speakers is in Mexico. Spanish is part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo, a prominent city of the Kingdom of Castile, in the 13th century. Spanish colonialism in the early modern period spurred on the introduction of the language to overseas locations, most notably to the Americas. As a Romance language, Spanish is a descendant of Latin, and has one of the smaller degrees of difference from it (about 20%) alongside Sardinian and Italian. Around 75% of modern Spanish vocabulary is derived from Latin, including Latin borrowings from Ancient Greek. Alongside English and French, it is also one of the most taught foreign languages throughout the world. Spanish does not feature prominently as a scientific language; however, it is better represented in areas like humanities and social sciences. Spanish is also the third most used language on internet websites after English and Chinese. Spanish is one of the six official languages of the United Nations, and it is also used as an official language by the European Union, Organization of American States, Union of South American Nations, Community of Latin American and Caribbean States, African Union and many other international organizations.
