“…Nowadays, the study of CMCs is a research domain it-self, crossing various disciplines such as sociology and linguistics. The linguistic questions related to CMCcorpora may for example concern paraverbal phenomena and the expression of emotions (Riordan and Kreuz, 2010;Tantawi and Rosson, 2019), politeness formulas and the degree of message formality (Brysbaert and Lahousse, 2019), the effects of orality in written communication (Soffer, 2010), the role of code-mixing and code-switching in mediated discourse (Morel and Doehler, 2013;Mave et al, 2018), their graphic and orthographic characteristics (Sullivan, 2017) (concerning Arabic).
