The word "lava" originates from Italian, derived from the Latin labes ("a fall" or "slide"), influenced by the Neapolitan dialect term lava ("stream"). It entered English in the 18th century to describe the molten rock flowing from volcanoes, reflecting its association with fluid movement. The Latin root labes hints at the dynamic, collapsing nature of volcanic eruptions.
The volcano spewed lava hundreds of feet into the air.
After the eruption, the hardened lava formed jagged rocks.
Scientists study lava to understand Earth’s geological processes.
