This paper proposes the development of a new field of research and study within applied linguistics: netlinguistics. This is to be a functional, stylistic and pragmatic linguistic and sociological analytical framework concerned with the technology of Internet, the lexicological production of new e-terms ¡, the evolution of cybergenres, digital tenor (as manifested in the informalisation process of Internet discourse), digital mode (as realised via hypertext and hyperlinks), the power relations established between different digital communities, and the overall Englishisation of Internet. Complementary, the paper describes some of the pedagogical implications of netlinguistic research in the teaching of English for Internet Purposes in ESP / LSP teaching contexts and other language learning settings.
