Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed forms, and may also be conveyed through writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.
A 2026 estimate of the number of "spoken or signed" languages remaining was around 7,500 (half of which are described as "endangered"), representing an estimated ninety-percent reduction over the past several thousand years. Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are spoken, signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing, whistling, signing, or braille. In other words, human language is modality-independent, but written or signed language is a way to inscribe or encode the natural human speech or gestures.
Depending on philosophical perspectives regarding the definition of language and meaning, when used as a general concept, "language" may refer to the cognitive ability to learn and use systems of complex communication, or to describe the set of rules that makes up these systems, or the set of utterances that can be produced from those rules. All languages rely on the process of semiosis to relate signs to particular meanings. Oral, manual and tactile languages contain a phonological system that governs how symbols are used to form sequences known as words or morphemes, and a syntactic system that governs how words and morphemes are combined to form phrases and utterances.
The scientific study of language is called linguistics. Critical examinations of languages, such as philosophy of language, the relationships between language and thought, how words represent experience, etc., have been debated at least since Gorgias and Plato in ancient Greek civilization. Thinkers such as Jean-Jacques Rousseau (1712–1778) have argued that language originated from emotions, while others like Immanuel Kant (1724–1804) have argued that language originated from rational and logical thought. Twentieth century philosophers such as Ludwig Wittgenstein (1889–1951) argued that philosophy is really the study of language itself. Major figures in contemporary linguistics include Ferdinand de Saussure and Noam Chomsky. (Full article...)
The Lakota language (Lakȟótiyapi [laˈkˣɔtɪjapɪ]), also referred to as Lakhota, Teton or Teton Sioux, is a Siouan language spoken by the Lakota people of the Sioux tribes. Lakota is mutually intelligible with the two dialects of the Dakota language, especially Western Dakota, and is one of the three major varieties of the Sioux language.
Speakers of the Lakota language make up one of the largest Native American language speech communities in the United States, with approximately 2,000 speakers, who live mostly in the northern plains states of North Dakota and South Dakota. Many communities have immersion programs for both children and adults. (Full article...)

The grammar of the Sanskrit language has a complex verbal system, rich nominal declension, and extensive use of compound nouns. It was studied and codified by Sanskrit grammarians from the later Vedic period (roughly 8th century BCE), culminating in the Pāṇinian grammar of the 4th century BCE. (Full article...)
