Endorse → It is formed from "en-" (meaning to cause to be in) and "dorse" (from Latin "dorsum", meaning back). The word originally referred to the act of signing on the back of a document, thus giving approval or support.
Think of 'causing to be in' ('en-') and 'back' ('dorse') — this helps you remember that to endorse means to give your support or approval.
