Why “sooth” is a great word
An archaic term for what is true, real, or for the truth itself, from Middle English *sooth*, from Old English *sōþ* ('truth; true, actual, real'), from Proto-West Germanic *sanþ*, from Proto-Germanic *sanþaz* ('truth; true'), from Proto-Indo-European *h₁sónts*, *h₁s-ont-* ('being, existence, real, true'), from the root *h₁es-* ('to be'). Unlike 'verity,' which implies a doctrinal or profound certainty, or 'fact,' a cold, settled point of data, sooth carries the warmth and gravity of something real—the unadorned grain of an oak table under one's hand, the stark, unsweetened prophecy of a bird's flight, or the quiet, felt honesty in a friend's promise. It is the quiet, forgotten ground of being from which all our prettier flowers of speech have grown.
Etymology
From Middle English sooth, from Old English sōþ (“truth; true, actual, real”), from Proto-West Germanic *sanþ, from Proto-Germanic *sanþaz (“truth; true”), from Proto-Indo-European *h₁sónts, *h₁s-ont- (“being, existence, real, true”), from Proto-Indo-European *h₁es- (“to be”).
Akin to Old Saxon sōþ (“true”), Old High German sand (“true”), Old Norse sannr (“true”), Gothic 𐍃𐌿𐌽𐌾𐌰 (sunja, “truth”), Old English synn (“sin, guilt"; literally, "being the one guilty”). More at sin. See also soothe, derived from the same Old English word.
