To reduce to the status of a creature; to make creature-like or bestial (rare or theoretical).
From 'creature' plus '-ize' (Greek -izein, forming verbs of action or process). This transitive verb suggests transformation into creatureliness.
This word barely exists in English, but the '-ize' suffix is so productive that English speakers instinctively understand it—you could read 'creaturize' and immediately grasp what it means even if you've never encountered it before, showing how suffix logic works in our heads.
