In the United States, United Kingdom and most of their former territories, English is the main language. However, there are some significant differences in spelling and word usage among British and American english. This article aims to provide a list of some of these differences that may be useful to travellers.
Usage by countries
British English is primarily used in the United Kingdom, Ireland, Australia, New Zealand, Hong Kong, Singapore, India, Pakistan. American English on the other hand is used in the United States and Philippines. Canada uses a mixture of British english (primarily for spelling ) and American english (primarily for vocabulary).
However in countries outside the United States and United Kingdom that use either American or British English, there are slight or minor variations that are particular to that country.

attorney/lawyer - barrister (or advocate in Scotland)/solicitor (UK-wide)
The AmE terms "attorney" and "lawyer" are interchangeable, but the corresponding BrE terms are not. The legal professions in the two countries are fundamentally different. In the UK, clients generally deal directly with solicitors, who provide legal advice and can represent their clients in lower courts. Barristers, titled advocates in Scotland, are specifically trained in trial advocacy, and are usually hired by solicitors to appear in higher courts, draft pleadings, and provide more specific advice on a given case. Historically, only barristers/advocates could appear before all courts; today, solicitors who receive additional special training can appear in the same courts as solicitor advocates. By contrast, the U.S. has a "fused" legal profession; the functions that are divided between two different classes of professionals in the UK are all part of a single profession in the U.S.
