3 - The Buri spoken language is meant to be easily spoken by Umbreons, although that might seem like an obvious fact. However, this greatly influences the use of sounds.

The very earliest Buri spoken language was a slightly more organized form of Umbreon language, being formed mostly of rearranged Um, Bree, and Eon sounds. However, as Buri culture developed, and more complex things needed to be described, the three foundational sounds were insufficient, so terms were warped, so as to still use the same tongue formation, but not the same syllables (for example, the term "Buri" is quite clearly related to "bree," but also uses the 'u' from "um").

As the Buri became more exposed to external (especially human) culture, more new words were needed to describe new things. While previously only used to refer to the mate of a Buri's surname, other sounds were used to refer to these new things, besides sounds based of of the three base sounds of Um, Bree, and Eon. 

In Buri language, it is easy (for Buri) to hear the difference in words whether they are older or newer based on what sounds they utilize, as older words use the softer original sounds, as well as other soft sounds such as 'j' or 'n', whereas newer words use the harsher sounds like 'k' and 'p' more often.

The Buri written language, conversely, is much younger than the language as a whole. It was not developed until after contact with human culture became significantly less avoidable, and writing was discovered to be an efficient way of recording information besides trusting it to be remembered in the collective consciousness. At first, it utilized the German alphabet (that is, a Latin alphabet, but accepting the use of things such as umlaut ("Ü") and Eszett ("ß," which was favored over regular 's' by more artistic Buri writers), although there were no set grammatical rules. 

However, a significant issue with such a writing system was that the curves and circles of Latin alphabet is hard to write (as Buri, without opposable thumbs, usually wrote by carving with a claw into a slab of wood). For this reason, writing was usually delegated to a non-Buri resident who happened to have opposable digits and could hold something like a pen, or a Buri with the newly created profession of calligraphy, which, at the time, was a booming trade among the Buri.

To make the Buri language more accessible, a different script was adapted to be more easily written by average Buri. It takes each Latin character, and represents it with one, two, three, or four strokes, four being the number of claws on a Buri paw. With this script, text can be produced simply by scratching the medium, requiring only a few slight turns of the wrist or contractions of the fingers to rapidly produce text. Since this language is an easy way for any four toed, clawed creature to write, Buri characters are commonly used by other such creatures who wish to write. Most notably, the Joseon, who, starting with Asimo Countach, were often welcomed into Buri community despite not necessarily being mates of Buri, so as to use their hard claws to quickly write history and Burrewu Bawu o Buri into stone and other things more permanent than wood (which Buri claws are not durable enough to mark at writing speed).
