An Academic Look at SUM1

SUM1 is defined as an "internet slang term" by our team because some of its characters are used as substitutes for letters. 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.

Someone is an indefinite pronoun, as it is a substitute for a noun and refers to a non-specific person or thing. Here are some other common indefinite pronouns:
  • anyone
  •  anything
  •  everybody
  •  nobody
  •  several
  •  somebody
