An Old High German citation form in the inherited Germanic hate-verb family, printed beside hazzēn and spelling variants hazēn, hazōn, haʒʒēn, and haʒʒōn. Starling’s source record dates hazzēn to the eighth century and hazzōn to the ninth; Duden and Grimm’s DWB group the ēn and ōn forms in the history of German hassen. Corpus-wide research independently shows that some Old High German class-III ēn verbs also occur with class-II ōn forms, but the accessible abstract does not establish that hazzōn is one of its twenty repeatedly attested double forms. DWB reports haʒôn aligned with Latin aemulari and the forms hatamas and hatent with insequamur and insequuntur. Those reports support an action range involving following or hostile pursuit; they are not directly inspected manuscript tokens. Pokorny’s account, as transmitted by Starling, explicitly warns that the Germanic evidence does not prove “pursue” was the root’s basic meaning. The route therefore distinguishes the normalized headword, the combined historical variants, the reconstructed Germanic weak verb and noun family, the qualified Indo-European comparison, and the point where knowledge ends.
