To make something old-fashioned or no longer useful; to cause something to become outdated or obsolete.
From Latin antiquatus (made old), past participle of antiquare. Entered English in the 16th century meaning literally 'to make ancient.' The sense of 'making obsolete' developed because old things naturally become outdated.
Technology companies love to 'antiquate' your devices—but the word itself is centuries old, showing that humans have always understood how newness automatically makes the old seem useless. Fashion and planned obsolescence are ancient concepts, just with fancier branding.
