語源
英語の原文（Wiktionary）
From Middle English ago, agon (“passed”), past participle of agon (“to depart, escape, pass”), from Old English āgān (“to go away, pass away, go forth, come to pass”), from Proto-Germanic *uz- (“out”), *gāną (“to go”), equivalent to a- + gone, and by surface analysis, a- + go. Cognate with German ergehen (“to come to pass, fare, go forth”). Compare also Old Saxon āgangan (“to go or pass by”), Gothic 𐌿𐍃𐌲𐌰𐌲𐌲𐌰𐌽 (usgaggan, “to go forth”).
