English remains very much a second language for most people, used in administration, education and government and as a means of communicating between speakers of diverse languages. As with most of the Commonwealth, British English is the model on which, for instance, Indian English or Nigerian English is based. In the Caribbean and especially in Canada, however, historical links with the UK compete with geographical, cultural and economic ties with the USA, so that some aspects of the local varieties of English follow British norms and others reflect US usage.
