Having jointed feet or limbs; characteristic of or belonging to arthropods or similar jointed-legged creatures.
From arthro- (jointed) + -podous (from Greek pous, foot, + -ous, possessing). This more formal adjectival construction emphasizes the anatomical feature of jointed appendages.
This adjective takes us back to the literal meaning—'having jointed feet'—which was the original observation that made ancient naturalists group these creatures together, centuries before we understood evolution or genetics.
