What does the root of this word mean deportment?

The root of the word "deportment" is the Latin word "deportare," which means "to carry away" or "to transport."

While it doesn't directly translate to the modern meaning of "deportment," which refers to someone's behavior, manner, or conduct, the root hints at the concept of "carrying oneself" in a certain way.

Think of it like this: Your deportment is how you "carry" yourself, your personality, and your attitude through the world.
