Language

This is a list of languages arranged by age of the oldest existing text recording a complete sentence in the language. It does not include undeciphered writing systems, though there are various claims without wide acceptance, which, if substantiated, would push backward the first attestation of certain languages. It also does not include inscriptions consisting of isolated words or names from a language. In most cases, some form of the language had already been spoken (and even written) considerably earlier than the dates of the earliest extant samples provided here.

A written record may encode a stage of a language corresponding to an earlier time, either as a result of oral tradition, or because the earliest source is a copy of an older manuscript that was lost. An oral tradition of epic poetry may typically bridge a few centuries, and in rare cases, over a millennium. An extreme case is the Vedic Sanskrit of the Rigveda: the earliest parts of this text date to c. 1500 BC, while the oldest known manuscripts date to c. 1040 AD.Similarly the oldest Avestan texts, the Gathas, are believed to have been composed before 1000 BC, but the oldest Avestan manuscripts date from the 13th century AD.

In linguistics, transcription is the systematic representation of spoken language in written form. The source can either be utterances (speech or sign language) or preexisting text in another writing system.

Transcription should not be confused with translation, which means representing the meaning of text from a source-language in a target language, (e.g. Los Angeles (from source-language Spanish) means The Angels in the target language English); or with transliteration, which means representing the spelling of a text from one script to another.

Pronunciation is the way in which a word or a language is spoken.

This may refer to generally agreed-upon sequences of sounds used in speaking a given word or all language in a specific dialect—"correct" or "standard" pronunciation—or simply the way a particular individual speaks a word or language.

An ethnicity or ethnic group is a group of people who identify with each other on the basis of perceived shared attributes that distinguish them from other groups. Attributes that ethnicities believe to share include language, culture, common sets of ancestry, traditions, society, religion, history, or social treatment. Ethnicities are maintained through long-term endogamy and may have a narrow or broad spectrum of genetic ancestry, with some groups having mixed genetic ancestry. Ethnicity is sometimes used interchangeably with nation, particularly in cases of ethnic nationalism. It is also used interchangeably with race although not all ethnicities identify as racial groups.

By way of assimilation, acculturation, amalgamation, language shift, intermarriage, adoption and religious conversion, individuals or groups may over time shift from one ethnic group to another. Ethnic groups may be divided into subgroups or tribes, which over time may become separate ethnic groups themselves due to endogamy or physical isolation from the parent group. Conversely, formerly separate ethnicities can merge to form a panethnicity and may eventually merge into one single ethnicity. Whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis.

Linguistics is the scientific study of language. The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics (how the context of use contributes to meaning). Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions.

Linguistics encompasses many branches and subfields that span both theoretical and practical applications. Theoretical linguistics is concerned with understanding the universal and fundamental nature of language and developing a general theoretical framework for describing it. Applied linguistics seeks to utilize the scientific findings of the study of language for practical purposes, such as developing methods of improving language education and literacy.

Truth or verity is the property of being in accord with fact or reality. In everyday language, it is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.

True statements are usually held to be the opposite of false statements. The concept of truth is discussed and debated in various contexts, including philosophy, art, theology, law, and science. Most human activities depend upon the concept, where its nature as a concept is assumed rather than being a subject of discussion, including journalism and everyday life. Some philosophers view the concept of truth as basic, and unable to be explained in any terms that are more easily understood than the concept of truth itself. Most commonly, truth is viewed as the correspondence of language or thought to a mind-independent world. This is called the correspondence theory of truth.

Sumerian (Sumerian: 𒅴𒂠, romanized: eme-gir₁₅, lit. ''native language'') was the language of ancient Sumer. It is one of the oldest attested languages, dating back to at least 2900 BC. It is a local language isolate that was spoken in ancient Mesopotamia, in the area that is now modern-day Iraq.

Sumerian is read from left to right, from the top, however early inscriptions were read top to bottom from the right.

Proto-writing consists of visible marks communicating limited information. Such systems emerged from earlier traditions of symbol systems in the early Neolithic, as early as the 7th millennium BC in China and southeastern Europe. They used ideographic or early mnemonic symbols or both to represent a limited number of concepts, in contrast to true writing systems, which record the language of the writer.

Writing is the act of creating a persistent, visual, static representation of language. A writing system includes a particular set of symbols that are called a script, as well as the rules by which they encode a particular spoken language. Every written language arises from a corresponding spoken language; while the use of language is universal across human societies, most spoken languages are not written.

Writing is a cognitive and social activity involving neuropsychological and physical processes. The outcome of this activity, also called writing (or a text) is a series of physically inscribed, mechanically transferred, or digitally represented symbols. Reading is the corresponding process of interpreting a written text, with the interpreter referred to as a reader.

Speech is the use of the human voice as a medium for language. Spoken language combines vowel and consonant sounds to form units of meaning like words, which belong to a language's lexicon. There are many different intentional speech acts, such as informing, declaring, asking, persuading, directing; acts may vary in various aspects like enunciation, intonation, loudness, and tempo to convey meaning. Individuals may also unintentionally communicate aspects of their social position through speech, such as sex, age, place of origin, physiological and mental condition, education, and experiences.

While normally used to facilitate communication with others, people may also use speech without the intent to communicate. Speech may nevertheless express emotions or desires; people talk to themselves sometimes in acts that are a development of what some psychologists (e.g., Lev Vygotsky) have maintained is the use of silent speech in an interior monologue to vivify and organize cognition, sometimes in the momentary adoption of a dual persona as self addressing self as though addressing another person. Solo speech can be used to memorize or to test one's memorization of things, and in prayer or in meditation.
