arctic

The word 'arctic' has a celestial origin, deriving from the Greek 'arktikos', meaning 'of the bear'. This refers not to the polar animal, but to the Great Bear constellation (Ursa Major), which is prominent in the northern night sky. The Greeks used the term 'arktikos' to describe the northern lands lying under this constellation. Over time, through Latin 'arcticus', the term evolved from its astronomical reference to specifically denote the frigid region around the North Pole, and later, by metaphorical extension, anything extremely cold.

Structure: arct (bear) + ic (adjective suffix) 'arct' originates from the Greek 'arktos', meaning 'bear'. 'ic' is an English adjective-forming suffix derived from Latin '-icus' and Greek '-ikos'.
