An Academic Look at M9

M9 is classified as an "internet slang term" by our team. It is not an abbreviation. Most "slang terms" were introduced to reduce the number of key strokes required to write the word, but since the arrival of predictive texting and keyboards on mobile devices, this efficiency is no longer required. Nevertheless, "slang terms" are still regularly used to make messages more entertaining or to express individuality. "Slang terms" differ from icons because they are not pictorial representations.
