Derived from Greek amphibios (literally "living a double life"), combining amphi- ("both") + bios ("life"). The term originally described creatures like frogs that thrive in water and on land. By the 17th century, it extended to military tactics (e.g., amphibious assaults), reflecting dual-nature adaptability. The morphemes preserve their Greek roots while aligning with modern English spelling.
