Indo-European Languages

The Indo-European languages are a large language family that includes many languages spoken in Europe, Western Asia, and northern India. Linguists maintain that all these languages descended from a single earlier language, unattested in writing, called Proto-Indo-European, which has been reconstructed through the comparative method.

This family includes languages such as English, Spanish, French, Russian, Hindi, Bengali, Persian, and Greek. Because of migration and colonization in later centuries, many languages in this family are now spoken in the Americas, Australia, and other parts of the world.

Recognition

In the 18th and 19th centuries, scholars noticed consistent similarities among Sanskrit, Ancient Greek, and Latin—particularly in word roots and verbal endings. These similarities could not be due to chance; therefore it was proposed that these languages shared a common origin. Subsequently, sound laws were formulated to explain how a single earlier sound changed in regular ways within each language.

Major branches

The family is divided into branches, including: Indo-Iranian (Sanskrit, Hindi-Urdu, Bengali, Persian, Kurdish), Germanic (English, German, Scandinavian), Italic/Romance (Latin, Spanish, French, Italian, Portuguese, Romanian), Slavic (Russian, Polish, Serbo-Croatian), Baltic (Lithuanian, Latvian), Celtic (Irish, Welsh), Greek, Armenian, and Albanian. Some older branches that are now extinct also existed, such as Hittite and Tocharian.

Linguistic features

The earlier languages of this family had a complex system of inflection: nouns changed form according to case, number, and gender, while verbs had distinct forms for tense and person. Many modern languages in the family—such as English—have simplified this system, relying instead on word order and prepositions.
