Did you know?

We can't say there are exactly 100 English words based on the Latin root centum, meaning "hundred," but there are certainly dozens. "Centenarian" isn't the oldest one; it only dates from the late 1700s. Far older is "centurion" (an ancient Roman military officer), which has been around since the 13th century. A younger "centum" offspring is "centisecond," a rare term for 1/100 of a second that dates from the 1950s. From colorful words such as "centicipitous" (which means "100-headed") to practical ones like "centgener" ("a device for planting 100 seeds"), "centum" descendants have enlivened our language for centuries.
