Etymology

Origin of groundhog

An Americanism dating back to 1650–60; ground 1 + hog

Explanation

Groundhogs are large rodents that are native to North America. Legend has it that if a groundhog emerges from hibernation and sees its shadow on February 2, there will be six more weeks of winter. Gardeners and ranchers consider groundhogs to be pests, because they nibble on vegetables and plants and have a habit of tunneling underground to construct elaborate burrows. These stocky rodents are closely related to marmots, prairie dogs, and squirrels. In some parts of the U.S. they're known as woodchucks, and in other regions people call them whistle pigs. Historians trace the first Groundhog Day to the mid 19th century.
