What does plunged mean?
“Plunged” is the past tense and past participle of “plunge.” Its most familiar meaning describes someone or something moving rapidly downward, as a diver enters the water. It also describes abrupt, steep declines in quantities such as prices, temperatures, and attendance. The verb can further suggest beginning an activity or undertaking with suddenness, energy, or commitment, as in “she plunged into the project.” “Plunged” is common in both British and American English and appears regularly in journalistic descriptions of dramatic falls. In figurative contexts it often carries a sense of suddenness and severity rather than merely gradual movement. The word is especially useful when an event changes quickly and noticeably, whether physically, financially, or emotionally.

Where does plunged come from?
The verb ultimately comes through Middle English from Old French plon(g)er. This developed from a late Latin term associated with plumbum, the Latin word for lead, reflecting the earlier use of a lead-weighted line to measure depth. English developed cognates such as “plumb” and “plummet,” which preserve connections with depth and descent.
