In English, on the other hand, the regional variants continued to diverge. There is no concentrated effort to establish a supranational standard, and the use of English around the world evolves more or less at will. One exception is in pronunciation, where extreme divergence is already leading to considerable difficulties in communication, as a Bostonian vacationing on Jamaica might attest. One suggestion for dealing with this divergence is to establish a common minimum standard, a “core lingua franca” to ensure the viability of transnational communications.
