Did You Know?
Most things quadrennial occur every four years (that's the more common use). We can say, for example, that the U.S. presidential election is a quadrennial event. But we can also say that president's term in office is quadrennial, making good use of the "lasting four years" sense. The Latin combining form quadri- adds a factor of four to many English words: quadriceps (the thigh muscle, which has four parts), quadrilateral (a four-sided polygon), quadragenarian (a person in his or her 40s), and quadricentennial (a 400th anniversary), to name a few. The -ennial part of quadrennial has the same root as in biennial and centennial; all trace back to annus, the Latin word for "year."
