2. Remarks or sentences, often definitions, that convey the truth about something in a concise and humorous way: Sharon's mother shaped her mind with a steady stream of aphorisms; such as, "Waste not, want not."
To be accepted as an aphorism, it is necessary for a saying to contain a truth that is revealed in a concise statement; such as, when Jack LaLanne, a famous American fitness, exercise, and nutritional expert once stated the aphorism: "I can’t die, because it would ruin my image."
3. Etymology: from Middle French aphorisme, aufforisme, from Middle Latin aphorismus, from Greek aphorismos, "definition, pithy sentence", from aphorizein, "to mark off, to divide", from ap-, "off" + horos, "boundary, to bound" + -ism, "act" or "practice of".
