The word "plunge" originated from the Old French word "plongier", meaning "to plunge, to sink". It can be traced back to the Latin word "plumbum", which means "lead", as in the metal. The connection exists because one of the meanings of "plumbum" was a lead weight attached to a line used to measure the depth of water. Over time, "plunge" came to mean diving or submerging oneself suddenly and deeply into water.
The addition of "in" to "plunge" forms the phrase "plunge in", which simply intensifies the action of plunging and emphasizes the complete, immersive nature of the action. This phrase is frequently used figuratively to describe a person's full involvement or engagement in an activity or situation.
