Do you have cacography (errative) in your mother tongue? In Russian in the web it was popular “olbansky” language (or “padonkaffskiy” — “padonki” is an errative from “podonki”— sсums). People wrote in “olbansky” with purposely mistakes — for example, «Превед» instead «Привет» (hi), or «йа криведко» instead «я креветка» (I’m a shrimp), etc. This “language” had quite strict rules of writing which depended on Russian spelling, so if you are a well-educated person, you could recognize if a person had a fun with “olbansky” or he/she just didn’t know how to write a word in a proper way. People could write in “olbansky” long texts and even communicate. Do you have such phenomenon in your language? Do you break words just for laugh or expressing your mood?
