Did you know?

If you’ve ever had a peaceful, easy feeling—perhaps brought on by someone who you know won’t let you down—then you’ll have no problem understanding the earliest meaning of lenient. When it entered English in the mid-1600s, lenient described something soothing—such as a medication—that relieved pain or stress, or otherwise enabled someone to take it easy. For a brief window of time it was even used as a noun, referring to any of various ointments and balms that help heal wounds in the long run. Lenient comes from the Latin verb lenire, meaning “to soften or soothe,” which in turn comes from the adjective lenis, meaning “soft or mild.” The “soothing or easing” sense of lenient is still in use today, but English speakers are more likely to apply it to someone who is lax with the rules (as in “a lenient professor”), who doesn’t mind when someone acts like a certain kind of fool or takes it to the limit one more time.
