Origin

Late 17th century: from modern Latin stalactites, from Greek stalaktos 'dripping', based on stalassein 'to drip'.

  • Stalactites hang down from the roof of a cave. The name comes from Greek stalaktos ‘dropping or dripping’. Stalagmites (late 17th century), on the other hand, rise up from the floor of a cave, formed from the evaporated dripping from above. Greek stalagma ‘a drop or drip’ is the source this time.
