British spelling American spelling

Every language allows different kinds of variations: geographical or territorial, perhaps the most obvious, stylistic, the difference between the written and the spoken form of the standard national language and others. It is the national language of England proper, the USA, Australia, New Zealand and some provinces of Canada. It is the official language of Wales, Scotland, in Gibraltar and on the island of Malta. Modern linguistics distinguishes territorial variants of a national language and local dialects. Variants of a language are regional varieties of a standard literary language characterized by some minor peculiarities in the sound system, vocabulary and grammar and by their own literary norms.
