Falser → It is formed from "false" (from Old English *fals*, meaning not true or incorrect) and "-er" (meaning a person who). The word "falser" refers to a person who is more false or deceitful than another.
Think of someone who is 'not true' ('false') and the '-er' indicating a person. A falser is someone who is more deceitful.
