The 'other' languages of England - those which originate in South and East Asia, and Southern and Eastern Europe - are now important parts of everyday life in urban England. First published in 1985, this book gives detailed information about which languages are in widespread use among children and adults, patterns of language use in different social contexts, the teaching of these community languages inside and outside of mainstream schools, and the educational implications of this linguistic diversity for all children in England. They authors argue that this continued and widespread bilingualism is a valuable potential resource for both the speakers and society as a whole.

they belong. Do communities have rights, indeed even an existence, which are not merely the hypostasis of the individual rights and existences collected in them? This conflict is then more striking as it was a conscious decision of the or ganizers of the workshop to focus attention on what might broadly be called liberal democracies: those societies which share a commitment to the princi ples of democratic participation, to the right of equal concern and respect of all members of the community, and to the basic liberties of association, ex pression, and thought. Ours was not the smug premise, however, that every so ciety which proclaims these principles is sufficiently or even truly devoted to them. But we did assume that we would have enough to do if we explored the implications of these widely shared ideals for the topic of linguistic, ethnic, and national minorities as these problems arise in societies where an appeal to them is not an empty gesture. The nations from which our participants were drawn are societies in which appeal to these principles has some point. They are all societies in which the efforts of politicians and the intelligence of schol ars need not be devoted exclusively to the tactical issues of winning some mod icum of respect for basic human rights from unwilling regimes. And yet all these societies have experienced significant difficulty in determining what the concrete meaning in actual situations of these general principles might be."
