'alberich' originates from Old High German, specifically the word 'alb(e)rīh,' where 'alb' meant 'elf' and 'rīh' meant 'ruler.'

'alb(e)rīh' transformed into the Middle High German word 'alberich,' and eventually became the modern English word 'alberich.'

Initially, it meant 'elf ruler,' but over time it evolved into its current association with a specific mythological character.
