An inauguration is a formal ceremony where someone officially begins an important position or role.

In the United States, a presidential inauguration happens when a new president takes office. The president-elect stands before crowds at the U.S. Capitol, places their hand on a Bible, and recites the oath of office. After those 35 words, they become president. Past inaugurations have included dramatic moments: Thomas Jefferson walked to his own inauguration to show democratic simplicity, Franklin Roosevelt declared “the only thing we have to fear is fear itself” during the Great Depression, and John F. Kennedy challenged Americans to “ask not what your country can do for you, ask what you can do for your country.”

Inaugurations happen for many kinds of positions and events. A mayor, governor, or student council president might have an inauguration when they take office. Even buildings get inaugurated: when a new museum or stadium opens, there's often an inaugural ceremony or event. The key idea is that something significant is officially beginning, usually with witnesses present to mark the moment.
