fatten
UK: ˈfæt(ə)n | US: ˈfætn̩
vt. to make or become fat or plump
vi. to increase in weight or size (of animals, especially for slaughter)
The word "fatten" combines "fat," derived from Old English fǣtt (meaning "plump" or "greasy"), with the suffix "-en," which turns adjectives into verbs (e.g., "soften," "darken"). This suffix originates from Old English -nian, used to form causative verbs. The term originally described making livestock plump for slaughter, later extending metaphorically to humans or objects.
