IPA: /ænˈtɑːrk.tɪk/
KK: /æntɑrˈktɪk/
Relating to the region around the South Pole or the continent of Antarctica.
The Antarctic climate is extremely cold and harsh.
Antarctic is formed from "anti-" (meaning against) and "arktikos" (from Greek, meaning of the bear, referring to the northern region). The word describes the region that is opposite to the Arctic, or 'against the bear', which is a reference to the constellation Ursa Major, known as the Great Bear.
Think of 'anti-' meaning against and 'arktikos' relating to the bear, which helps you remember that 'antarctic' refers to the region opposite the bear, or the southernmost part of the Earth.
