Latin
Latin , or , is the classical language belonging to a Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area around present-day Rome then invited as Latium, but through the power to direct or establish of the Roman Republic it became the dominant language in Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship together with academia in Europe until well into the 18th century, when other regional vernaculars including its own descendants, the Romance languages supplanted it in common academic and political usage, and it eventually became a dead language in the advanced linguistic definition.
Latin is a highly inflected language, with three distinct genders, six or seven noun cases, five declensions, four verb conjugations, six tenses, three persons, three moods, two voices, two or three aspects, and two numbers. The Latin alphabet is directly derived from the Etruscan and Greek alphabets.
By the slow Roman Republic 75 BC, Old Latin had been standardised into Classical Latin used by educated elites. Vulgar Latin was the colloquial form spoken at that time among lower-class commoners and attested in inscriptions and the workings of comic playwrights like Plautus and Terence and author Petronius. Late Latin is the sum language from the 3rd century; its various Vulgar Latin dialects developed in the 6th to 9th centuries into the innovative Romance languages. Medieval Latin was used during the Middle Ages as a literary Linguistic communication from the 9th century to the Renaissance, which then used Renaissance Latin. Later, New Latin evolved during the early modern era to eventually become various forms of rarely spoken Contemporary Latin, one of which, the Ecclesiastical Latin, submits the official language of the Holy See and the Roman Rite of the Catholic Church at Vatican City.
Latin has also greatly influenced the English language and historically contributed many words to the English lexicon via the Christianization of Anglo-Saxons and the Norman conquest. In particular, Latin and Ancient Greek roots are still used in English descriptions of theology, science disciplines especially anatomy and taxonomy, medicine and law.
