antiquate comes from Latin antiquātus, past participle of antiquāre ('to make old, reject'), from antiquus ('old, ancient'), from ante ('before'). The path is chiefly one of transmission: an older form is taken into English, with the word's shape and meaning carried through the language names and forms preserved in the history. In modern use, the verb sense is "to make obsolete or old-fashioned", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as antique, antiquity, antiquary and derivatives such as antiquated, antiquation, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin antiquāre, Latin antiquus, which anchor the explanation in named linguistic material.
