'coercively-obtained' originates from the Latin word 'coercere,' where 'co-' meant 'together' and 'arcere' meant 'to enclose or confine.'

'coercere' transformed into the Old French word 'coercif,' and eventually became the modern English word 'coercive.'

Initially, it meant 'to confine or restrain,' but over time it evolved into its current meaning of 'using force or threats to obtain something.'
