What does plummiest mean?
Plummiest is the superlative form of plummet and describes something that falls or declines in the steepest, most rapid, or most dramatic way. It can function as an adjective, as in “the plummiest descent,” or as an adverb, as in “prices fell plummestly.” The word is not limited to literal movement: it can intensify the force of an economic, professional, or personal collapse, making it especially effective in journalism and literary description. Compared with steepest, plummiest often adds a sense of suddenness, speed, or severity. Because it is an inflected form rather than an independent vocabulary word, it is less common in everyday speech, where a standard superlative such as steepest, sharpest, or fastest may sound more natural.
Denoting the most steep, rapid, or dramatic descent or decline.
"The mountain's plummiest route is marked with red and white rope."
Usually modifies descent, fall, decline, or a similar noun.
In the steepest or most dramatically downward manner.
"The stock market fell plummestly after the announcement."
Used with verbs describing a fall, descent, or decline; it is more emphatic and literary than simply 'most steeply'.
Plummiest turns the familiar idea of a steep drop into a superlative that captures the most dramatic descent imaginable.

Where does plummiest come from?
The word derives from plummet, a term historically associated with a lead weight used to establish a vertical line or to measure depth. English plummet came through Middle French from the Latin word plumbum, meaning lead; the same root also underlies English plumb, plumbing, and the modern French word plomb. In its figurative use, plummet developed the sense of falling steeply and rapidly, from which the superlative plummiest was formed.
