Etymology
Origin of plummet
1350–1400; (noun) Middle English plommet < Middle French, diminutive of plomb lead; (v.) derivative of the noun See plumb, -et
Explanation
The verb plummet means "to drop sharply," like eagles that plummet toward earth, seeking prey, or school attendance that plummets when there is a flu outbreak. To correctly pronounce plummet, say "PLUH-met." This verb describes something that drops sharply or quickly, like a roller coaster that plummets down a hill, temperatures that plummet overnight, or sales of roses and candy that plummet after Valentine's Day. If something plummets, this doesn't mean it will stay down or low forever, just that it has experienced a sharp drop.
