Did You Know?

We borrowed "regimen" straight from Latin, spelling and all - but in Latin, the word simply meant "rule" or "government." In English, it usually refers to a system of rules or guidelines, often for living a healthy life or taking a regular dose of exercise. The Latin regimen derives from another Latin word, the verb "regere," which means "to lead straight" or "to rule." If you trace straight back from "regere," you'll find that "regimen" has plenty of lexical kin, including "correct," "erect," "region," "rule," and "surge." If you are using the "training" sense of "regimen," be careful not to confuse the word with "regiment," another "regere" descendant, which is used for a military unit.
