Definition of the word amphibious

The word "amphibious" originates from the Greek words "amphibios," meaning "living a double life" or "dual-natured." The term was first used in the 17th century to describe animals that live in both water and on land, such as frogs and toads. Over time, the meaning of the word expanded to include devices and vehicles that can operate in both aquatic and terrestrial environments, such as amphibious boats, tanks, and aircraft. The word's association with dual habitats likely arose from the fact that many early biologists and naturalists studied aquatic animals that could also live on land. By extension, the term "amphibious" began to be applied to objects and machines that could similarly function in multiple environments. Today, the word is used in a range of contexts, from biology and engineering to military applications and pop culture.
