"The term wall comes from Latin vallum meaning "...an earthen wall or rampart set with palisades, a row or line of stakes, a wall, a rampart, fortification..." while the Latin word murus means a defensive stone wall.[1] English uses the same word to mean an external wall and the internal sides of a room, but this is not universal. Many languages distinguish between the two. In German, some of this distinction can be seen between Wand and Mauer, in Spanish between pared and muro."wikipedia/walls
In fact it's what I plan to study. There are so many forms and ways to come across architecture. To depict what architecture even is. It's simply art, but in the form of a structure. A very building that people can walk in. Spend their moments in, determine status in society, protect from drastic weather, earn money under, and so much more.
