The word "oath" traces back to Old English āþ, meaning a solemn pledge or vow, often sworn to a deity as a witness. It shares roots with Old Norse eiðr and Gothic aiþs, reflecting a common Germanic tradition of binding promises. Unlike many modern English words, "oath" remains structurally intact from its ancient form, preserving its core meaning of a sacred or formal declaration. Its simplicity underscores its cultural and linguistic endurance.
