British spelling; relating to the process of civilizing or the advancement of civilization.
From civilise + -atory (relating to or tending toward). The -atory suffix comes from Latin -atorius. British -s- spelling convention.
The word 'civilisatory' carries historical baggage: European powers once justified colonialism as a 'civilisatory mission,' a phrase that masked exploitation—making this word a linguistic artifact of how language was weaponized to justify imperialism.
