Question: What was the language Auctor comes from during the era of the king who was crowned emperor of the west in 800 CE?

<P0-S0> Charlemagne (/ ˈʃɑːrləmeɪn /) or Charles the Great (2 April 742 -- 28 January 814), numbered Charles I, was King of the Franks from 768, King of the Lombards from 774, and Holy Roman Emperor from 800. <P0-S1> He united much of western and central Europe during the early Middle Ages. <P0-S2> He was the first recognized emperor to rule from western Europe since the fall of the Western Roman Empire three centuries earlier. <P0-S3> The expanded Frankish state that Charlemagne founded is called the Carolingian Empire. <P0-S4> He was later invalidly canonized by the antipope Paschal III. <SEP> <P1-S0> Auctor is Latin for author or originator. <P1-S1> The term is used in Scholasticism for a "renowned scholar", and in biological taxonomy for the scientist describing a species or other taxon. <P1-S2> The term is widely replaced by author in English-language works. <SEP> <P2-S0> it is not known when she was born to yuan dan (元亶) the prince of qinghe, a grandson of emperor xiaowen, but what is known is that during the reign of emperor xiaowu (532-535), she was created the princess pingyi. <P2-S1> in 534, emperor xiaowu, seeking to escape the grasp of gao huan, fled west from the capital luoyang to the domain of the independent general yuwen tai. <P2-S2> gao huan subsequently made her brother yuan shanjian emperor (as emperor xiaojing), signifying a division of northern wei into eastern wei (with emperor xiaojing as emperor) and western wei (with emperor xiaowu as emperor). <P2-S3> she was subsequently given to gao huan's son gao cheng as his wife, although the date of the marriage is not known. <SEP> <P3-S0> in 768 pepin's son charlemagne became king of the franks and began an extensive expansion of the realm. <P3-S1> he eventually incorporated the territories of present - day france, germany, northern italy, and beyond, linking the frankish kingdom with papal lands. <P3-S2> on christmas day of 800, pope leo iii crowned charlemagne emperor, restoring the title in the west for the first time in over three centuries. <SEP> <P4-S0> Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". <P4-S1> Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. <P4-S2> The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. <P4-S3> Charlemagne's chancery—or writing office—made use of a new script today known as Carolingian minuscule,[M] allowing a common writing style that advanced communication across much of Europe. <P4-S4> Charlemagne sponsored changes in church liturgy, imposing the Roman form of church service on his domains, as well as the Gregorian chant in liturgical music for the churches. <P4-S5> An important activity for scholars during this period was the copying, correcting, and dissemination of basic works on religious and secular topics, with the aim of encouraging learning. <P4-S6> New works on religious topics and schoolbooks were also produced. <P4-S7> Grammarians of the period modified the Latin language, changing it from the Classical Latin of the Roman Empire into a more flexible form to fit the needs of the church and government. <P4-S8> By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin.
