Due to its size, the work presented here very briefly tackles some of the problems that arise during analysis and therefore issues that require further research in the future should be summarised. In this respect, linguistic issues come to the fore, in particular those related to the use of mixed variety. A thorough study of formulae taking into account phonetic realisation as well as variation in the choice of classical or dialectal items along with their situational and contextual determinants is called for. Nevertheless, this cannot be achieved with the type of data analysed here; instead, it would require a sizeable corpus of spontaneous oral utterances gathered in an inobtrusive way, which obviously poses a considerable challenge to the researcher.

Other problems are more directly related to the type of data used here. A problematic issue is the “third party factor” in CMC, mentioned previously, leading to the numerous acts of self-presentation and an exceptional attentiveness to the form of the verbal production posted online. This situation also causes some other linguistic phenomena that were not discussed exhaustively in this work. One of them is the “emblematic” role of the standard variety and its development in CMC. It is assumed that at least some speakers have a poor command of MSA, yet they use this variety frequently in their online posts. Therefore, it would be of great importance to examine the language used by them in the context of linguistic correctness, and perhaps, language change.

Other issues concern typically Arabic manners of expression, an example of which is the role and pragmatic function of adjuration. Adjuration in EA is used in all types of conversations, strengthening the message and conveying the sincerity of speaker. It can be considered as a specifically Arabic act in everyday verbal exchanges. However, it does not appear in situations involving strong taboo like death. Investigating this issue might contribute greatly to the analysis of emotionality of Arabic speech.

Ferguson argues, “[t]he obligatory inclusion of a God-wish in response to a health inquiry, however, seems of sufficient regularity and the linguistic conditions of its occurrence so readily stable, that it would seem to belong within the grammar.
