To make something domestic; to adapt or accustom something to home or domestic conditions, or to bring something into the domestic realm.
From domestic + -ize (suffix meaning 'to make or become'). This is a variant or related form of domesticate, emphasizing the transformation into domestic form.
Domesticize is rarer than domesticate, but it's used more abstractly—you domesticize a foreign custom by making it part of home life, while you domesticate an actual animal.
