Did You Know?
Indurate is a hard word—in more than one way. Not only is it fairly uncommon in modern usage, but it also can be traced back to Latin durare, meaning "to harden." Durare can mean "to endure" as well, and appropriately indurate is a word that has lasted many years—it has been a part of the English language since the 14th century. Durare is also the root of other durable English words, including during, endure, duration, durance, and even durable itself. In addition, indurate can be a verb meaning "to make or grow hard," "to make unfeeling, stubborn, or obdurate," and "to establish firmly."
