Etymology

Borrowed from Proto-Germanic *gaizaz (given the diphthong *ai instead of the expected *oi), which itself is derived from Proto-Indo-European *ǵʰoysós (“throwing spear”), from Proto-Indo-European *ǵʰey- (“to throw, impel”). Related to Sanskrit हेषस् (heṣas, “missile”), Avestan 𐬰𐬀𐬉𐬥𐬀‎ (zaēna, “weapon”), Ancient Greek χαῖος (khaîos, “shepherd's staff”).
