Typography is the visual component of the written word. According to Wikipedia The word “typography” in English comes from the Greek roots τύπος typos = “impression” and -γραφία -graphia = “writing”. I have no idea if that’s true but it sounds good to me.
Before computer-aided design and printing happened, Typography was an art form in its own right. Developed in the world of paper printing like newspapers and magazines. Three aspects of typography are legibility, readability, and aesthetics.
