This article extends and discusses a study by M. Valério (2015), which deals with several groups of personal names from southern Anatolia. It is proposed here to reconstruct one onomastic stem, *tubar(i)‐, common to several names from different language corpora belonging to the Luwic sub-group (Luwian, Carian, Pisidian) and Greek epigraphic sources from southern Anatolia (from Caria to Cilicia). This prolific element is associated with various divine names or epithets in compounds, which suggests that it corresponded to a divine title. Its meaning can be reconstructed as “battle companion, comrade-in-arms”, originally qualifying various deities whose role was to guard their protégé on the battlefield.
