IPA: /ˈsɛntɪpiːd/
KK: /ˈsɛntɪˌpid/
A type of long, flat creature with many segments, each having a pair of legs. These animals are known for being predators and can have venomous bites.
I saw a centipede crawling across the floor in the dark.
Centipede → It is formed from "centi-" (from Latin "centum", meaning one hundred) and "pedis" (from Latin, meaning foot). The word "centipede" literally means "one hundred feet," referring to the many legs of this creature, although they do not actually have one hundred legs.
Imagine a creature with 'one hundred' ('centi-') 'feet' ('pedis') — that's why a centipede is known for having many legs.
