Etymology
Origin of landslide
Explanation
When dirt and rock from a mountainside are sliding down, call it a landslide. Another kind of landslide takes place when one candidate soundly defeats another in an election. With either type of landslide, it's probably safest to stay out of the way! The political meaning of landslide is commonly used, but it's not the word's original definition. A geographical landslide occurs when a huge amount of earth slides down a slope or mountain, usually displacing rocks and vegetation and often houses and buildings as well. Landslides are caused by erosion, heavy rain, and earthquakes, among other events, and they're disruptive enough to give rise to the figurative meaning.
