Apprehendere, Latin for apprehend obviously, is the root or origin of apprenticeship. It simply morphed from Latin, via Old French to Middle English. I guess we could say that “apprentice” has been value added as it has ceased to mean apprehend in a narrow sense. Now it means intentional learning, to become a “journeyman” or woman, to grow into a master craftsman worthy of your guild. I wonder how many people in their trades today apprehend? I sure hope my plumber does!
