Old Latin in the context of "Latin Language"

Latin (lingua Latina or Latinum) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally spoken by the Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, including English, having contributed many words to the English lexicon, particularly after the Christianisation of the Anglo-Saxons and the Norman Conquest. Latin roots appear frequently in the technical vocabulary used by fields such as theology, the sciences, medicine, and law.

By the late Roman Republic, Old Latin had evolved into standardised Classical Latin. Vulgar Latin refers to the less prestigious colloquial registers, attested in inscriptions and some literary works such as those of the comic playwrights Plautus and Terence and the author Petronius. While often called a "dead language", Latin did not undergo language death. Between the 6th and 9th centuries, natural language change in the vernacular Latin of different regions evolved into distinct Romance languages. After the fall of the Western Roman Empire, Latin remained the common language of international communication, science, scholarship and academia in Europe into the early 19th century, by which time modern languages had supplanted it in common academic and political usage.

Classical Latin is the form of Literary Latin recognized as a literary standard by writers of the late Roman Republic and early Roman Empire. It developed around 75 BC from Old Latin, and developed by the 3rd century AD into Late Latin. In some later periods, the former was regarded as good or proper Latin, while the latter was seen as debased, degenerate, or corrupted. The word Latin is now understood by default to mean "Classical Latin"; for example, modern Latin textbooks almost exclusively teach Classical Latin.

Cicero and his contemporaries of the late republic referred to the Latin language, in contrast to other languages such as Greek, as lingua latina or sermo latinus. They distinguished the common vernacular, however, as Vulgar Latin (sermo vulgaris and sermo vulgi), in contrast to the higher register that they called latinitas, sometimes translated as "Latinity". Latinitas was also called sermo familiaris ("speech of the good families"), sermo urbanus ("speech of the city"), and in rare cases sermo nobilis ("noble speech"). Besides the noun Latinitas, it was referred to with the adverb latine ("in (good) Latin", literally "Latinly") or its comparative latinius ("in better Latin", literally "more Latinly").

Titus Maccius Plautus (/ˈplɔːtəs/ PLAW-təs; c. 254 – 184 BC) was a Roman playwright of the Old Latin period. His comedies are the earliest Latin literary works to have survived in their entirety. He wrote Palliata comoedia, the genre devised by Livius Andronicus, the innovator of Latin literature. The word Plautine /ˈplɔːtaɪn/ (PLAW-tyne) refers to both Plautus's own works and works similar to or influenced by his.He influenced some of the greatest figures in literature, including Shakespeare and Molière (The Miser is partly modeled after Plautus's Aulularia).

Latin phonology is the system of sounds used in Latin. Classical Latin was spoken from the late Roman Republic to the early Empire: evidence for its pronunciation is taken from comments by Roman grammarians, common spelling mistakes, transcriptions into other languages, and the outcomes of various sounds in the Romance languages.

Latin orthography is the writing system used to spell Latin from its archaic stages down to the present. Latin was nearly always spelt in the Latin alphabet, but further details varied from period to period. The alphabet developed from Old Italic script, which had developed from a variant of the Greek alphabet, which in turn had developed from a variant of the Phoenician alphabet. The Latin alphabet most resembles the Greek alphabet that can be seen on black-figure pottery dating to c. 540 BC, especially the Euboean regional variant.
