Language Name Generator

Yes, and you should. Most real language names are the people's name plus -ish, -ese, -ian, -ic, -i or -an (Polish, Portuguese, Russian, Arabic, Hindi, German), some are named for a place (Latin from Latium), and a few use descriptive or register words (Old English, High German, Low German, Swiss German, Haitian Creole). Fantasy names that follow those patterns read as real without further explanation.

No. Most published fantasy only needs a name, a sound (a few sample words or names for characters and places), and a sense of who speaks it. A name like Drethani and a handful of consistent-sounding words will carry a whole novel; a full conlang is only worth building if the language itself is on the page a lot.

A cant or argot is the secret slang of a group (thieves, traders, soldiers). A pidgin is a simplified contact language nobody speaks natively; when children grow up speaking it natively it becomes a creole. A koine is a common dialect that spreads across a region as a shared standard, the way Koine Greek did. Using the right word gives your setting a realistic linguistic texture.

Yes. All the names here are original or generic descriptive terms, not taken from trademarked properties, and they are free to use in commercial fiction, tabletop supplements and video games. If you need to be certain a name is unique, search it before publishing.
