The language utilized by the Ergesh was known as the Ergesh language, as documented in language records.
Descriptions of the Ergesh language often likened its sound to viscous mud emanating from a vigorous boil. Given their intrinsic wetness and the paramount importance of fluids to the Ergesh, the term "dry" was absent from their lexicon; however, they possessed a word signifying "not wet," frequently employed as an expletive. Despite this, the majority of the Ergesh species typically opted for Basic, albeit with a distinct underwater-like quality to their pronunciation.
