vice president
A leader who is second in charge after the president.
A vice president is the person who serves as second-in-command to a president, ready to step in if the president cannot fulfill their duties. In the United States government, the Vice President becomes President if the President dies, resigns, or cannot continue serving. The Vice President also serves as President of the Senate, casting tie-breaking votes when senators are evenly split on important decisions.
Many organizations beyond government have vice presidents too. Large companies often have multiple vice presidents who lead different departments like sales, engineering, or finance. A student council might have a vice president who helps the president organize events and takes charge when the president is absent.
Think of it like having a co-captain on a sports team: they share leadership responsibilities and are ready to lead the team if the main captain can't play.
Throughout American history, fifteen Vice Presidents have become President, including Theodore Roosevelt, Harry Truman, and Lyndon Johnson, who each took office after a President died and then later won a presidential election.
