Behind the updating and revising of the OED is another, much bigger story: the inexorable growth of English itself. At a conservative estimate, 1bn people now speak it as a second or foreign language, while the 375m for whom it is a mother tongue continue to mould their own varieties in ways that the dictionary’s original compilers could never have imagined. As such, the OED finds itself in the curious position of being a national institution called upon, almost by default, to assume the role of a global one.
