The language we speak and write is governed by a number of rules, styles and constraints. Quite apart from the meaning we wish to convey (Thank you for your invitation. I will come at eight o´clock), we have to think about whether we are writing or speaking, texting or emailing. Whereas text messaging has developed into a sophisticated way of conveying messages in the shortest possible space (hence thx4=thanks for), more formal letters are written out in full (Thank you very much for inviting me) and e-mails accept mis-spelling and deviant punctuation (for example, not using a capital I for i´ll).
But whether language users are texting, emailing, speaking or letter-writing, they are making choices about the language they use based on what they want to say, what medium they are operating in, how texts are typically constructed in such situations, what grammar they can use and what words and expressions they can find to express their meaning. Therefore, English learners should be taught to produce or understand utterances which are not so much grammatical but, more important, appropriate to the context to which they are made.
