Etymology

The word "Martian" derives from "Mars," the Roman god of war and namesake of the red planet, combined with the suffix "-ian," which denotes relation or belonging. The term emerged in the late 19th century as astronomical interest in Mars grew, particularly fueled by speculative theories about life on the planet. The suffix "-ian" (from Latin "-ianus") is commonly used in English to form adjectives and nouns indicating origin or association (e.g., "Venetian," "reptilian").
