'Alderamin' originates from Arabic, specifically the phrase 'al-dira al-yamin,' where 'al-dira' meant 'the right arm' and 'al-yamin' meant 'right.'

'al-dira al-yamin' transformed into the medieval Latin 'Alderamin,' and eventually became the modern English name 'Alderamin.'

Initially, it referred to the 'right arm' of the constellation Cepheus, and this meaning has largely remained the same in modern usage.
