The dynamism of the expansion of English into new roles and territories seems to have reached a qualitatively new dimension in the very recent past, over the last two or three decades. English is coming to be used in novel ways and new contexts, and in functions which substantially go beyond its former roles. One major manifestation of this trend is the increasing use of English as a Lingua Franca (ELF), a type of context which has generated a new, focused sub-discipline of its own (with textbooks, a journal and a conference series devoted to it) over the last few years. In addition, uses of English in media and web manifestations, in grassroots forms by speakers who have not had any formal access to it, or for "specific purposes" constitute fascinating realizations of this development. Some of these I have addressed in some recent research, and they continue to attract my interest.
