The Latin root word ann and its variant enn both mean “year.” These roots are the word origin of various English vocabulary words, including anniversary and centennial. The roots ann and enn are easily remembered through the words anniversary, which is the turning of another “year,” and millennium, a period of 1000 “years.”
