Aqͣqarͤrhat is a language spoken by a civilization of the same name, that once has ruled in the region of the great river Thailassar; the very name (which is the Middle Aqͣqarͤrhat form, by the way) means "Riverland". Several periods of formation of this language are known, ranging from Proto-Aqͣqarͤrhat, from which also a few other languages come from, through Old and Middle (also called High) stages up to what is nowadays known as the New Aqͣqarͤrhat, with some major changes occuring between these steps.
