Concerning → It is formed from "con-" (meaning with or together) and "cernere" (meaning to separate or distinguish). The word "concerning" means relating to or about something, as it involves distinguishing or addressing a particular subject.
Think of 'with' ('con-') and 'distinguishing' ('cernere') to remember that 'concerning' means relating to a specific topic.
