From Halopedia, the Halo wiki
Yonhetian is the language of the Yonhet species. The Yonhetian language seemingly makes use of illeism in everyday speech, as Yonhet individuals casually refer to themselves in the third person instead of the first person. Apart from their native tongue, Yonhet traders and smugglers also speak the Covenant trade pidgin language.
