Medieval Latin was the form of Literary Latin used in Roman Catholic Western Europe during the Middle Ages. In this region it served as the primary written language, though local languages were also written to varying degrees. Latin functioned as the main medium of scholarly exchange, as the liturgical language of the Church, and as the working language of science, literature, law, and administration. Medieval Latin represented a continuation of Classical Latin and Late Latin, with enhancements for new concepts as well as for the increasing integration of Christianity. Despite some meaningful differences from Classical Latin, Medieval writers did not regard it as a fundamentally different language. There is no real consensus on the exact boundary where Late Latin ends and Medieval Latin begins. Some scholarly surveys begin with the rise of early Ecclesiastical Latin in the middle of the 4th century, others around 500, and still others with the replacement of written Late Latin by written Romance languages starting around the year 900. The terms Medieval Latin and Ecclesiastical Latin are sometimes used synonymously, though some scholars draw distinctions. Ecclesiastical Latin refers specifically to the form that has been used by the Roman Catholic Church (even before the Middle Ages in the Antiquity), whereas Medieval Latin refers to all of the (written) forms of Latin used in the Middle Ages. The Romance languages spoken in the Middle Ages were often referred to as Latin, since the Romance languages were all descended from Vulgar Latin itself. Medieval Latin would be replaced by educated humanist Renaissance Latin which then developed into New Latin. Influences Christian Latin Medieval Latin had an enlarged vocabulary, which freely borrowed from other sources. It was heavily influenced by the language of the Vulgate, which contained many peculiarities alien to Classical Latin that resulted from a more or less direct translation from Greek and Hebrew; the peculiarities mirrored the original not only in its vocabulary but also in its grammar and syntax. Greek provided much of the technical vocabulary of Christianity. The various Germanic languages spoken by the Germanic tribes, who invaded southern Europe, were also major sources of new words. Germanic leaders became the rulers of parts of the Roman Empire that they conquered, and words from their languages were freely imported into the vocabulary of law. Other more ordinary words were replaced by coinages from Vulgar Latin or Germanic sources because the classical words had
