'algedi' originates from Arabic, specifically the word 'الجدي' (al-jady), where 'al-' meant 'the' and 'jady' meant 'goat.'

'الجدي' transformed into the Latin word 'Algedi,' and eventually became the modern English word 'algedi.'

Initially, it meant 'the goat,' referring to the constellation Capricornus, and this meaning has largely remained the same in modern usage.
