Here all Rangers can work together :)
And I'm translating first what it looks in my mind important for all together.
There is strictly speaking no Ranger's language, but it is the mixture of the four nations leading them to create common terms. Generally, the Rangers chat in their language and often understand the languages of the various nations. Some people of them are famous translators who travel the bark by renting their services for moderate exchanges of barrels of beer (rather Trykers, of course) and of cookies (rather with prohibited termites in it).
On the other hand, the fact of living ceaselessly on the lookout for Kitins and of sneaking everywhere under the bark to observe discreetly their lifestyle led the Rangers to use numerous onomatopoeias at the same time to be furtive and fast in roots or in the heart of nature.
The Rangers were hardly influenced by the culture Matis, doubtless because of Almati, also the mateis served as phonetic base for their language.
In the same time, Rangers language has this peculiarity that it is very brief, especially in mission. The words are short, most of the time monosyllabic, to be as quick or/and discrete as possible.
There are only five vowels without rules of length, accents.... So many variations could be found around each one.
There are fifteen consonants, with large variability of pronunciation to be able for everybody:
