The present participle of bestialize; the ongoing process of making something savage or animal-like.
From bestialize + -ing (present participle suffix). The -ing form comes from Old English -ung, making this a hybrid of Latin root with Germanic suffix structure.
The -ing form is uniquely powerful in English because it makes abstract concepts feel active and present—'bestializing' forces sounds more immediate than 'bestiality,' which is why writers use it when describing ongoing moral corruption.
