'alphyn' originates from Middle English, specifically the word 'alfin,' where 'al-' meant 'all' and '-fin' referred to 'end' or 'limit.'

'alfin' transformed into the modern English word 'alphyn' through the influence of heraldic traditions.

Initially, it meant 'a mythical creature with no limits,' but over time it evolved into its current meaning of 'a heraldic beast.'
