The word “peaceable” has been employed in literature with a remarkable range, yet its core connotation of quiet, gentle, and non-aggressive character remains consistent. In character portrayals, it is used to denote a calm and honest nature, as seen when a figure is described as “an honest, peaceable, knowing man” ([1]) or when a simple, virtuous disposition is highlighted in characters from Dickens’ works ([2]) and Chekhov’s stories ([3], [4]). At times, authors leverage “peaceable” in political or societal contexts to suggest order and moderation—sometimes with a hint of irony—as in the notion of a “peaceable revolution” ([5], [6]) or the depiction of entire communities and nations as inherently tranquil ([7], [8]). Meanwhile, intellectual admiration is expressed through references to “peaceable lawgivers” such as Numa, Solon, and Lycurgus ([9], [10], [11]), and even landscapes are touched by the word’s calm aesthetic, as in a scene where a lantern reveals a “peaceable surface” ([12]). Overall, “peaceable” functions both as a marker of moral and behavioral virtue and as a descriptor for environments and reforms aimed at harmonious coexistence.
