Non-Indo-European languages are those that do not belong to the Indo-European language family, which includes languages like English, Spanish, and Hindi. Instead, these languages come from various other families, such as Sino-Tibetan, Afro-Asiatic, and Uralic. Examples include Mandarin Chinese, Arabic, and Finnish. These languages often have unique grammatical structures, vocabulary, and phonetics that set them apart from Indo-European languages. They are spoken by millions of people worldwide and contribute to the rich diversity of human communication. Understanding these languages can provide insights into different cultures and histories.
