Having six feet or legs; relating to or characteristic of animals with six-legged body structure.
From Greek 'hexa-' (six) + 'pous' (foot) + '-ous' (having the quality of). This adjectival form directly mirrors the structure of 'hexapetalous' and 'hexaphyllous' in botanical terminology.
The '-ous' ending in hexapodous is the same one used in dangerous, nervous, or fabulous—it's a super-productive suffix that English borrowed from Latin to turn concepts into adjectives.
