Luwian language
It is thought that the name "Leleges" is an exonym, in a long-extinct language, rather than an endonym (or autonym). That is, during the Bronze Age the word "lulahi" apparently meaning "strangers" was used in the Luwian language and in other Anatolian languages. For example, in a Hittite cuneiform inscription, priests and temple servants are directed to avoid conversing with "lulahi" and foreign merchants. According to the suggestion of Vitaly Shevoroshkin, an attempt to transliterate "lulahi" into Greek might result in "leleges".
