The entire Mesovalkian region is a massive sprachbund: a region where multiple languages are spoken in tandem and there are frequent contacts between speakers of different languages. This and lack of language centralization attempt by nation-state polities historically resulted in highly complex dialect continuum of Mesovalkian languages, where there exists gradations of mutual intelligibility between adjacent regions within Mesovalkia that gradually diminished proportional to the distance. While there exists a trend of broad convergence towards more homogeneous trade languages or bazaari, the most prominent being Darbar-Samaya Standard Dialect, this trend is also almost always followed with dialect divergences among different subcultures, making complete linguistic homogenization complicated at best. Furthermore, the prevalence of translation software and polyglot neural modulation generally has rendered any policy intended to promote linguistic homogenization unnecessary even for state-building purposes.

In the southern region of Seaxland, Saxon, a language nearly identical to Standard Multiversal English, is spoken by some, and more children learn it every year due to revitalization programs, which are especially strong due to the demand for Standard Multiversal English among governments of our Earth with even tangential relation to the world assembly, The Anglians Speak Anglish, which is very similar to Saxon but with a distinct lack of french loanwords, and is undergoing a similar process on a smaller scale. Welsh is Spoken in Wales, though its revitalization program lags behind the others.

Marlenki (Con-lag) is the official language of Marlenka, specifically the Dormentok dialect. Malrenki has 5 main dialects but only 3 are spoken in official settings.
Dormentok, or the "Highland talk/tongue" was spoken in its current form since about the end of the middle ages, though it went through many iterations before the current from was chosen. Technically it is a [in lore] conlag since it was created by King Nürhüānsgër in order to facilitate communication with the numerous Marlenki tribes and provinces without having to learn all of their dialects.
Hárska is a very complicated dialect hailing from the island of St.Heilja, that is the original form of Marlenki when it was first ever written. Not many people speak it outside of St.Heilja but it is the language of almost all ancient Marlenki literature, and despite it being centuries old has had no major changes to it. It only has been adapted to the Latin Script in 2011.
Hëjiko is less of a dialect and more a collective term for Slang spoken by Marlenki sailors near Küne-Hërmilan. It what is lacks in technical value it makes up for in its compendium of insults, anecdotes, and songs.
Various forms of Russian, Swedish, Finnish/Hungarian and English are also spoken in Marlenka as Marlenki itself is an amalgamation of these languages with it's own twists.

Russian is the sole official language of Alaska, and is the native language of the majority of the population (around 80%). However, there is some formal recognition of prominent minority languages, ie. English (6%), Ukrainian (7%) and Japanese (2%), as well as Native Alaskan languages such as Yup'ik, Inupiat, Tlingit and Aleut, which are spoken by about 5% of people. In particular, there are government initiatives to preserve and promote indigenous languages, many of which are in danger of going extinct.

Schools in Alaska usually teach English and Spanish as foreign languages, as well as French and German, to a lesser extent. Some schools, particularly in New Archangel and Alexandrovsk, instead opt to use English as the language of instruction.
