Why “leniment” is a great word
LENIMENT — [Noun] Something that soothes or alleviates; a sedative or comforter. From Latin lēnīmentum, from lēnīre ("to soothe, soften") + -mentum ("instrument, means"). First attested in English c. 1623. Unlike "lenitive," which denotes a medicinal agent for pain, or "palliative," which implies relieving symptoms without a cure, "leniment" is the broader term for any gentle solace. It is the cool hand on a fevered brow, the steady murmur of a river in darkness, or the first sip of tea after a long and wretched day—a small, deliberate mercy against the raw friction of being.
