Origins of Oath and Affirmation

The word oath comes from Old English āþ, meaning a sacred or serious promise. Historically, oaths were tied closely to religion and the idea of divine witness. Swearing on a sacred object or text reinforced the seriousness of the promise.

Affirmation, on the other hand, derives from Latin affirmare, meaning “to make firm.” It was introduced as a secular alternative for those who preferred not to make religious vows. Over time, affirmations became a respected option in courts and official ceremonies to honor personal beliefs and freedom of conscience.
