Did You Know?
When a royal record keeper reported the "profligation of the knights" almost five centuries ago, he didn't mean the knights were wildly indulging in excesses; he meant they were thoroughly defeated in battle. There's nothing etymologically extreme there; the Latin verb "profligare," which is the root of both "profligate" and the much rarer "profligation" (meaning "ruin"), means "to strike down," "to destroy," or "to overwhelm." When the adjective "profligate" first appeared in print in English in the 1500s, it meant "overthrown" or "overwhelmed," but over time the word's meaning shifted to "immoral" or "wildly extravagant."
