Jirra (or swi-Jirra) is a language spoken by a population of Yitha (the Azirian equivalent of humans) who call themselves the Hyitha Jirra. The word "yitha" and related words (such as Chispa "yieta") are derived from the Jirra word "hyitha" [ˈçiθa], which is pronounced "yitha" [ˈʝiθa] in compounds.
