The Latin word mandāre, meaning “to commit” or “to order,” gives us the root mand. Words from the Latin mandāre have something to do with committing or ordering. When a task is mandatory, someone has ordered that it must be done. To command is to order someone to do something. A mandate is an order from an authority to follow specific instructions.
