A "Defender" typically refers to a player position in team sports, particularly in soccer and American football. In soccer, defenders are responsible for preventing the opposing team from scoring by blocking shots, tackling opponents, and clearing the ball from the defensive area. In American football, defenders aim to stop the offensive team from advancing the ball and scoring points.
In a broader context, the term "defender" can also refer to someone who protects or advocates for a cause, person, or principle. This can include legal defenders, such as attorneys who represent clients in court, or activists who defend human rights and social justice issues.
