English borrowed "stalactite" from Latin, which adopted it from the Greek word "stalaktos." Think about how a stalactite forms, then answer this: what do you think "stalaktos" means?Stalactites form from mineral-filled water dripping from the ceiling of a cave, so it makes sense that the word "stalactite" comes from a Greek term that means "dripping." Stalagmites are similar to stalactites, but stalactites hang down from a cave ceiling and stalagmites grow up from a cave floor. To keep track of which one goes up and which one goes down, try to mentally connect the "c" in "stalactite" with the word "ceiling" and the "g" in "stalagmite" with the word "ground."
