Dwarfish

The dwarven language is a very specific one, as it is mostely used underground and in presence of air pollutin machinery, where breathable air is scarce, it uses many ways to limit the intake of said air, whether it is done by using voiced consonants, by making words shorter than in most other languages, or by using sounds that do not use the vocal cords at all. While those methods do succed in reducing the intake of hardly breathable air, they also make dwarven a very hard language to learn and sometimes even painful to speak for non-natives, as well as making most words sound similarly, and thus easy to misunderstand . Due to its difficulty and easy misinterpretation it is not widely used outside of the (name of the region where dwarves traditionally live), and so when dwarves migrate to the outside world they usually forgo their native language, however if a large group of dwarves migrate outside, rather than abandoning their language they slowly adapt it into the environment where they breathe freely, itroducing many more vowels and voiceless consonants, usually shaping it similarly to the majority language of the surrounding populace. Those adapted to surface languages are collecively called "Dwarfish", with the distincion between them made in the first descriptor of the language, such as "Garafarrian Dwarfish". The dwarfish languages can usually understand most dwarven, and vice-versa; however they have trouble understanding one another.
