Language is a way of living, it is also an interesting way to know more about some nations' traditions and ways of living, and there are many websites and apps to help us to learn more and more about language and its parts.

A languages can have different parts, but not sections, I'm not exactly sure why, though. I think sections are separate, and parts work together, like the parts of the car. A engine compartment and a trunk, for example, are sections (or areas) of a car.
