Initially, all creatures were supposed to speak GodSpeech, the language spoken by the Gods. But that proved to be too difficult, or impossible to pronounce, for some species. Different cultures debased Godspeech into local languages and dialects. Today, there are still some common roots of all languages, a few key words are the same all over the world, and only the high priests of a few religions learn to speak an accented version of Godspeech.
The main languages of Norindaal are:
Dorantian
The main human language of Southern An-Mòr, also spoken in all colonies of Dorantia all over the world.
Trade
The main common language, limited and unsuited for song or literature, but used all over the eight continents in one way or another, Trade language was magically and socially encouraged. Scrolls and potions that allow any user to speak a basic form of Trade are widely available for those who, for some reason, did not bother to learn it. It's a very rudimentary language, with no real verbal tense. Poets and bards would be better off dead than be caught using Trade for anything else than speaking with a peasant or haggling over the price of a gig.
Elvish
Dathuuri, or Debased Elvish (spoken by Wood elves and Wild Elves)
Drau (spoken by dark elves; "drau" means "shining" in their language, as they call themselves the Drau Derlethi, which means the Shining Exalted People)
Cam-phran, spoken by fire elves (actually a dialect of dathuuri, it shares about 50% of its vocabulary, although often words have different endings)
Tobran, the language spoken by sea elves. In the current age, it's spoken only in a few underwater communities, as most sea elves living on land have adopted the most commonly spoken language in their area.
Nightspeak (a magical language, spoken by Night Elves, Vampires of all races, and other creatures of the night)
Eliphardas (High Elvish language, spoken only by First Caste "Starchildren" High Elves, and a few spellcasters; it is a very difficult language with four genders, social status and speaker's age reflected in suffixes and verbal forms, vowels with five different tones and even a sub-language that is used only to create new words and baby names). Mastering native fluency in this language without magical aid is nearly impossible for a non-high elf, unthinkable for a non-elf.
D'Harris
Dwarven language, spoken by all dwarven clans all over the world, with regional accents and variations but always using the same grammar).
Horroc
Language spoken by orcs and goblins, similar to Gobelar. Orcs, however, prefer it to Gobelar (which they can understand) and it is considered an offense for a goblin to speak to an orc in Gobelar.
Gobelar
Language spoken by Goblins and Gremlins, understandable to Orcs who generally don't bother to learn it in any case (some learn it to eavesdrop on their goblin servants chatter but keep their knowledge secret).
Ssiklia
Language spoken by all the Lizard people, who also communicate by hisses, sniffing, and with tongue vibrations, so the spoken language is quite crude and can only convey basic meaning (but no emotion). The written form of Ssiklia, normally used only by high priests, imports some words from Trade to stand in for the lacking Ssiklia equivalents.
Demon
Spoken by Demons, angels and demon worshippers. As demons are summoned anc can be controlled only spelling their true names with absolute accuracy, demonologists study this language so well that most can speak as a resident of the Netherworlds (those who make pronunciation mistakes usually discover that an error can end their magic careers).
