What is the difference between “cave” and “cavern”?
Good question! There is a difference between the two. “Cave” is quite general and refers to any hole or cavity in the ground that does not receive sunlight. On the other hand, a cavern is a specific type of rock cave that has developed cave formations like stalagmites and stalactites. If you see rock formations in a cave, you can wager that it is probably the “cavern” type of cave mentioned in this video.
