The name of the patriarch, "Hayk", is not exactly homophonous with the name for "Armenia", "Hayk’". Հայք "Hayk’" is the nominative plural in Classical Armenian of ("hay"), the Armenian term for "Armenian." Some claim that the etymology of "Hayk"' (Հայք) from Hayk (Հայկ) is impossible and that the origin of the term "Hay" ("Armenian") is verifiable. Nevertheless, Hayk and Haig are usually connected to "hay" (հայ) and "hayer" (, the nominative plural in Modern Armenian), the self-designation of the Armenians. Armen Petrosyan believes that the name Hayk can "very plausibly" be derived from the Indo-European *poti- ‘master, lord, master of the house, husband’.
