Presidential → It is formed from "president" (from Latin "praesidens", meaning sitting before or presiding) and "-ial" (meaning relating to). The word "presidential" refers to something that is related to or characteristic of a president.
Think of someone who is 'sitting before' ('praesidens') in a position of authority — that's why 'presidential' means relating to a president.
