In language, a root word is the basic unit of a word that derives into other words when prefixes or suffixes are added. In this case, the words bipeds, antipodes, and polypods share the root word "pod" or "ped" that means foot. Additionally, these words have been combined with different prefixes including the prefix "bi-" that means two which implies the word "bipeds" refers to animals that have two feet; the prefix "poly-" that means multiple which implies the word "polypods" refer to animals or any other that has multiple feets and the prefix "anti-" that means opposite or contrary to, which implies the word "antipodes" refers to objects or people stand (derived from foot) that are placed in opposite or contrary places and that is used in geography to describe places on Earth that are diametrically opposite. Therefore, the word that probably describes people who live on opposite sides of the world is "antipodes".
