What follows is an abbreviated list of some linguistic aspects of the English language along with their functions. As with any system of symbols, such as drawing, math, and language, this list is meant to convey an interpretation of reality. Just as the Mona Lisa is not the actual woman used as the model, squiggles on a map of England are not the actual England, and buildings and roads are composed of bricks and mortar rather than the equations used to combine building materials, this list is meant merely as a representation. Significant overlap exists. And as with any symbolic representation, any part of it that does not assist may reasonably be ignored. Keep in mind that the functions answer the question of why we learn the units. For example: Why do we learn idioms? To provide flexibility, creativity, and social status to our language.
