I think the point of avoiding acronyms and abbreviations isn't strong enough, because it doesn't explain how much they can creep into most conversation. As an example, here's how something can become gradually less specific, and gradually shortened. (I have an American Midwest accent, so not all of these shortenings will be applicable to all accents.) > I'm hungry. Would you like to get lunch and continue discussing this as we eat? Good clear statement, motivation, question, and proposed action. But there's some repetition. If I'm the one suggesting lunch, it can be assumed that I am hungry, so that doesn't need to be mentioned. > Would you like to get lunch and continue discussing this as we eat? Now we add in some cultural context, that people generally eat lunch around noon, and that it is generally a social affair. Asking if somebody wants to get lunch implicitly includes the question of having lunch as a group. > Would you like to get lunch? In the same manner, rather than asking about the intended action of "having lunch", one can instead ask about previous actions, with the assumption that somebody will join in on a social activity. > Have you eaten yet? Depending on the level of formality, both the choice of words and the level of diction can be chosen to progressively shorten the phrase. > Did you eat yet? > Didja eat yet? > Djeet yet? The last one, when spoken and in the context of a co-worker asking shortly before noon, is understandable as a social request by a native speaker with a similar accent, even though it's missing over half of the syllables needed to even be grammatically correct.
