Everyone hates them, that is for sure. But there is something that I am unsure about – why do we call them potholes?
First of all, not everyone calls them potholes, they are also known as kettles and chuckholes.
Second of all, if you read the definition of pothole, the reason it carries over to our roads is obvious:
a deep natural underground cavity formed by the erosion of rock, esp. by the action of water.
• a deep circular hole in a riverbed formed by the erosion of the rock by the rotation of stones in an eddy.
• a depression or hollow in a road surface caused by wear or subsidence.
• (also pothole lake) a pond in a natural hollow in the ground.
