Etymology

The word "frog" originates from Old English frogga, likely derived from Proto-Germanic fruʒgô. Its exact deeper roots are unclear, but it may be connected to an ancient imitative or expressive term for the animal's movement or sound. Unlike many Latin-derived scientific terms, "frog" retains its compact Germanic structure, resisting further morpheme division. Over time, its meaning expanded metaphorically (e.g., mechanical "frog") and culturally (slang for French people, from 18th-century stereotypes).
