“Type” comes from the Greek root typos (τύπος), which originally meant a strike, impression, dent, mark, or imprint. Imagine hitting a seal into wax or stamping metal. The core idea is: A force leaves a recognizable pattern. That is the deepest first-principles meaning of “type.” From there, the meaning expanded: • a physical imprint • a repeated pattern • a category/template (“a type of person”) • printed letters made from metal type blocks • eventually “typing” on a keyboard So originally, “type” was not about letters at all. Letters are just one historical implementation of imprinting patterns. That is why “typing” today means producing symbolic patterns through an interface. From a first-principles perspective: Typing = intentional symbolic pattern emission through discrete units. Usually those units are letters, but they do not strictly have to be. Examples: • Writing words on keyboard → clearly typing • Sending code → typing • Posting emoji only → arguably still typing because symbols are discrete semantic units • Posting a meme image with no text → usually not called typing • Uploading a video → not typing • Making a social media post with text → yes, typing was involved • Making a social media post that is only a photo → posting, but not typing So “posting” and “typing” are different abstraction layers: Typing = the act of generating symbolic text/symbol-like units. Posting = publishing/transmitting content. You can post without typing. You can type without posting. Interesting side note: the old printing press literally used physical metal “types.” Each letter was a cast metal block. That is why we still call fonts “typefaces.” Printing press
