'absoil' originates from Middle English, specifically the word 'absolen,' where 'ab-' meant 'away' and 'solen' meant 'to loosen or release.'

'absolen' transformed into the modern English word 'absoil' through linguistic evolution.

Initially, it meant 'to release from a binding or obligation,' but over time it evolved into its current meaning of 'to absolve from sin or guilt.'
