An oath is a formal promise or declaration, often made in a legal or ceremonial context, to tell the truth or uphold certain principles. People take oaths to affirm their commitment to honesty, integrity, or specific duties. Common examples include the Oath of Office taken by government officials and the Oath of Allegiance sworn by new citizens. Oaths can also be religious or personal, reflecting an individual's values or beliefs. In many cultures, oaths are considered sacred and binding, meaning that breaking an oath can lead to social or legal consequences. They serve to reinforce trust and accountability in various relationships and institutions.
