Did You Know?

Inviolable is a venerable word that has been with us since the 15th century. Its opposite, "violable" ("capable of being or likely to be violated") appeared a century later. The English playwright Shackerley Marmion made good use of "violable" in A Fine Companion in 1633, writing, "Alas, my heart is Tender and violable with the least weapon Sorrow can dart at me." But English speakers have never warmed up to that word the way we have to "inviolable," and it continues to be used much less frequently. Both terms descend from Latin violare, which both shares the meaning and is an ancestor of the English word violate.
