'acrolith' originates from Greek, specifically the word 'akrolithos,' where 'akro-' meant 'top' or 'extremity' and 'lithos' meant 'stone.'

'akrolithos' was used in ancient Greek to describe sculptures with stone extremities, and eventually became the modern English word 'acrolith.'

Initially, it meant 'stone extremity,' but over time it evolved into its current meaning of 'a sculpture with stone extremities.'
