Medieval Latin

Medieval Latin refers to the Latin used in the Middle Ages, primarily as a medium of scholarly exchange and as the liturgical language of the medieval Roman Catholic Church. It is therefore largely synonymous with Church Latin.

Medieval Latin was characterised by an enlarged vocabulary, which freely borrowed from other sources. Prominent among those sources were Greek, from which much of the technical vocabulary of Christianity came. The various Germanic languages spoken by the Germanic tribes who invaded western Europe were also major sources of new words. Germanic leaders became the rulers of western Europe, and as such 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 fallen into disuse. Latin was also spread to areas such as Ireland and Germany, where Romance languages were not spoken and which had never known Roman rule. Works written in these lands where Latin was a learned language with no relation to the local vernacular also influenced medieval Latin's vocabulary and syntax.

The influence of Vulgar Latin was also apparent in the syntax of some Medieval Latin writers, although Classical Latin continued to be held in high esteem and studied as models for literary compositions. The high point of development of medieval Latin as a literary language came with the Carolingian renaissance, a rebirth of learning kindled under the patronage of Charlemagne, king of the Franks. Alcuin was Charlemagne's Latin secretary and an important writer in his own right; his influence led to a rebirth of Latin literature and learning after the depressed period following the final disintegration of Roman authority in Western Europe.

Although it was simultaneously developing into the Romance languages, Latin itself remained very conservative, as it was no longer a native language and there were many ancient and medieval grammar books to give one standard form. On the other hand, strictly speaking there was no single form of "Medieval Latin." Every Latin author in the medieval period spoke Latin as a second language, to varying degrees of fluency, and syntax, grammar, and vocabulary were often influenced by an author's native language. This was especially true beginning around the 12th century, after which the language became increasingly adulterated: late-medieval Latin documents written by French speakers tend to show similarities to medieval French grammar and vocabulary; those written by Germans tend to show similarities to German, etc. For instance, rather than following the classical Latin practice of generally placing the verb at the end, medieval writers would often follow the conventions of their own native language instead. Whereas Latin had no definite or indefinite articles, medieval writers sometimes used forms of unus as an indefinite article, and forms of ille (reflecting usage in the Romance languages) or even "quidam" (meaning "a certain one/thing" in Classical Latin) as something like a definite article. Unlike in classical Latin, where esse ("to be") was used as the only auxiliary verb, Medieval Latin writers might use habere ("to have"), as Germanic and Romance languages do. The accusative infinitive construction in classical Latin was sometimes ignored, in favour of introducing a subordinate clause with the word "quod" (or occasionally "quia"). This is almost identical, for example, to the use of "que" in similar constructions in French.

The most striking differences between classical and medieval Latin are found in orthography. Some of the most frequently-occurring differences are:

These orthographical differences were often due to changes in pronunciation, which authors reflected in their writing. By the 16th century, Erasmus complained that speakers from different countries were unable to understand each others' form of Latin.

The gradual degradation of Latin did not escape the notice of contemporaries. Petrarch, writing in the 14th century, complained about this linguistic decline, which helped fuel his general dissatisfaction with his own era.
