If the word concoction makes you think of steaming caldrons or liquids bubbling in test tubes, you’ll be amused to know that it comes from a Latin word for “digestion.” Yum! On summer days, children sometimes concoct imaginative stews from grass, leaves and dirt. They may also concoct lies to explain why they tried feeding such concoctions to their little sister.
