In literature, "plumb" is a versatile term whose usage spans literal measurements, intensification in descriptive language, and symbolic representation. Often, it appears as an adjective suggesting exactness or completeness—portraying objects or states as perfectly vertical or utterly in a condition, as when a structure is rendered "plumb" in its alignment ([1], [2]). In narrative prose, the word also functions as an intensifier to stress totality or extremity, whether in denoting the absolute nature of beauty or the profound depth of human emotions ([3], [4]). Moreover, "plumb" serves a technical role in contexts like navigation and construction, referring to measuring depth or ensuring vertical precision, such as with a plumb-line ([5], [6]). Finally, its symbolic use connects physical correctness with moral rectitude, reflecting ideals that resonate, for instance, in Masonic imagery ([7], [8]).
