'Capricorni' originates from Latin, specifically the word 'Capricornus', where 'capri-' meant 'goat' and '-cornus' meant 'horn'.

'Capricornus' was used in Latin to describe the constellation, and 'Capricorni' is the genitive form used in modern astronomy.

Initially, it meant 'horned goat', but over time it evolved into its current usage in astronomy to denote stars within the constellation of Capricorn.
