honestly I don't get the point in your commenting "yes", "no", "never seen" next to a list which is only an example to explain a well-varied phenomenon which has no standardized rules. Well, I guess I may know something about it. PS: true, there are no rules, but simply those expression that I signed that way are not used.. or maybe (MAYBE) there's only a few people using them... very few... and anyway, if instead of writing "be4" (for instance) I made up something different (that maybe you understand anyway, but it's not common), what would you say? Would there be a point in saying something? would that mean that I may abbreviate everything in every way that I want? I don't think so. There ar no written rules, but there's something called "common use". That's what I meant.
It's not questioning what the right spelling of a word is or what a correct grammar form is Right! now tell me: did I ever say anything about grammar form or anything like that? I'm Italian, young and I use testese... I guess I know something about it... don't you think?
, textese is not a real language, it's a way people have to abbreviate words and depends only on the people themselves, their age, their social and cultural world, their level of education, their own life.
The fact that you might have not seen a form doesn't mean it is not correct, as there isn't what is correct and what isn't. Indeed, where I put "never seen" I didn't write anything like "that's not correct".
The principles for abbreviating I posted are simply inferred by linguistic observation and reflect natural linguistic change and simplification. It is true that some extreme abbreviations might be difficult to understand, but this doesn't mean that they are not used or shouldn't be used.
Aim of textese is communication and not misunderstanding. Urizon will get to understand what cc means soon.
