| Language | Areas Spoken | Notes |
| Imperial | Albia, Amacidia, Andor, Aryth, Cormyr, Illyria, Malkier, Ramosia, Strakenland, The Dragonlands, The Tionne Hegemony, Onea, Velmorra | Near universal language in the West dating back to the 2nd Imperium as currently spoken. Nearly universal second language outside of the countries listed (in the West). |
| High Imperial, "Chant" | Albia, Amacidia, Aryth, Cormyr, Illyria, Ramosia, The Tionne Hegemony, Onea | Court Language of the Imperiums. Any member of a High House (and most Low Houses), Court official, high-raking military officer, powerful trade magnates and guild heads, and any of the powerful Court hangers-on (noble Knights and Bards and such) will speak High Imperial. High Imperial stems from Imperial but many words, phrases, and even motions or items have subtle meanings, people speaking Imperial Common will be able to basically understand High Imperial but only a DC 25 Sense Motive check will reveal the full meaning. |
| Ramosi | Ramosia, Andor | Ramosia was independent until the formation of the 3rd Imperium so most Ramosian commoners, especially in rural areas, speak Ramosian Common. |
| Cormyri | Cormyr, Amacidia, Onea | The now ancient tongue of the Kingdom of Cormyr is spoken only by very few (usually learned or noble) Cormyrians. The Cormyri people have spoken Imperial Common since the middle period of the 1st Imperium (2nd Age) so it should be stressed that this is nearly a dead tongue and outside of Cormyri scholars and nobles it exists only in some books, old or important inscriptions, and tombs from the era. |
| Illyrian | Illyria, The Tionne Hegemony | As with Cormyri, Illyrian dissapeared within a few centuries of the Republic of Illyria merging with Cormyr into the 1st Imperium. Illyrian became the mother tongue for modern Imperial. It is, by and large, spoken only by the Illyrian nobility and scholars. An interesting wrinkle here is that ever since the reign of John I Tionne of Illeria became Emperor during the 2nd Imperium, Illyrian became the secret tongue of the Palace Guards was used to cipher Imperial military dispatches. This practice continues in the Tionne Hegemony. |
| Inerian | Aryth | A cross between old Illyrian and the tongue of the Grey Elves spoken in the Aryth Vale as the common tongue. Aryth was the only part of the Imperium that did not use Imperial as the basic language of trade and legal documents, although trade with the outside world was mostly conducted in Imperial or Beldroni. |
| Northern | Malkier, Strakenland | "Northern Speech" or the "Tongue of the "Northmen" is the language that comes from the first men who settled the plains beyond King John's Wall. In modern times, any 'true' northman speaks it and most of the rural communities only speak it. City dwellers tend to speak Imperial as well but many books, histories, and holy texts originating in the north are written in Northern. |
| Velmorran | Velmorra, Albia | A dying language that was on its last legs during the 3rd Imperium, Velmorran is making a comeback in the recent generation. It is seen mostly in the extensive works produced during the Velmorran Hegemony during the 2nd Age, but some more ethnic shops and establishments now hang their signs in Velmorran or Velmorran and Imperial. |
| Mantaéri | Mantaér | The oldest language on Dominaria, brought by the first settlers of the Westlands. It is much different that other human languages, many of those changed by time or contact with other species. Mantaéri people speak it nearly exclusively in their cities, and while most cosmopolitan Mantaéri can speak Imperial most commoners cannot. |
| Beldroni | Beldron | The language of the Beldroni cities and the Sword Coast. The language contains an oddly high number of swear words but all are used in ordinary conversation. |
| Arcadian | Arcadia, Andor, Selucia, Felix, Concord, Rishdan | Arcadian is the universal language across the Arcadian Empire. |
| Andoran | Andor | The Ancient Language of the Lion Kingdom is a barely remembered secret spoken now only by the Wizards of the Red Tower and the follow on guilds they have throughout Mantaér and Arcadia. |
| Selucian | Selucia, Rishdan | A thorough bastardization of Arcadian and Easterling that developed before Arcadia ever conquered Selucia. Your average Selucian is bilingual (Selucian and Arcadian) so it is now a regional language. Many Rishdani Guilds use it as a trade language. |
| Easterling | The Southern Caliphate, Kwazarmia, Sura, Cimmeria, the Slave Coast | The Language of the Enlightened, "Aluhah Al-Mustanir", is the common tongue in the Eastlands. |
| Kwazarmi | Kwazarmia, The Slave Coast | The Language of the Pantheon, "Aluhah Al-Thaadejhah", is the common tongue of all cities that fall under the Pantheist League, and is spoken in the Slave Coast as well. |
| Dhazanti | The Dhazantar Steppes, The Aktar Fells, the Ruul Valley | The language of the Steppe people of Dhazantar, it is also used to trade in Ruul. |
| Gutter Argot | All | Gutter Argot is an insane combination of human and demihuman languages spoken throughout the underworld of humanity. Gutter Argot is spoken in back alley sales and back room deals in every corner of Dominaria inhabited by Humans. Due to the nature of the language, each person has their own little nuances and puts their own spin on it. Therefore, even with the language, a DC 10 INT check every time a new person is spoken to in Gutter Argot. |
