A bit off-topic, but might be helpful; About Latin in Medieval Times
In Medieval times, many learned people (like priests, doctors and nobles) still used Latin then (Medieval Latin) as a second language.
Yet there was no single form of Medieval Latin since Latin varied by country and perhaps, by speaker. For example, The Latin of someone from France was influenced by French syntax, grammar and vocabulary, as well as the speaker’s fluency in Latin; A German speaker of Latin was influenced by German grammar, etc.
Taken from Wikipedia:
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.
Because of this, the Humanists complained that a speaker of Latin in one country couldn’t understand the Latin of a speaker from a different country. They sought to purge Latin of its Medieval Vocabulary and the ‘accretions’ that it had acquired in the centuries after the fall of the Roman Empire. For them, only the Latin of Cicero and Virgil and other works from the Roman Empire was the ‘real’ Latin; they condemned the other works done later in Latin as ‘gothic’.
They tried to insist that ‘ae’ be written in full as in Classical Latin whenever it was encountered; formerly, it was only written as ‘e’ (for example ‘Eternum’=‘Aeternum’, ‘Vite’=‘Vitae’), and ‘c’ to ‘t’ (‘Eciam’=‘Etiam’, ‘Divicie’=‘Divitiae’). Erasmus even proposed that the then-traditional (regional) pronunciations of Latin be abolished in favour of his reconstructed version of classical Latin pronunciation.
So far, the Humanists was successful, at least in education. But it became much harder to write books Science, Law, Medicine, and Politics in Latin while observing all of the Humanists’ norms about vocabulary purging and classical usage. Because the Latin proposed by Humanists lacked contemporary terms and vocabulary that can deal with modern issues,
Latin turned from a workday language to the subject of Antiquarian study, perhaps turning it more into the ‘dead language’ as it is known today.
