     We also document, as a key feature of SMS communication, hybrid forms of language use that blur the boundaries between what we commonly call languages (e.g. homographs, mixed spellings or allogenisms), and we suggest that these possibly indicate that SMS communication has become one site where the tension between localized and globalized social practices is played out.

     Allogenisms can be defined as lexical constructions made in one language using material from another language, and as such may be considered as a subclass of false loans. […] However, it turns out they are more extensively dealt with in unconventional sources, such as Wiktionary, and that they appear to occur more frequently in more marginal lexical fields such as brand names, film titles and slogans.]

     Notable is the fact that soft has become the base for an allogenism, the verb a resofta ('to reinstall', 'to jailbreak').
