Rosetta Stone offers two dialects of English for learners, English (British) and English (American).

English (British)

• spoken, with considerable regional variation, throughout the United Kingdom.
• common, with considerable regional variation, in countries that were once part of the British Empire (such as South Africa, New Zealand, Australia and the British Isles)

English (American)

• spoken throughout the United States
• widely understood by English speakers in other parts of the world.  Most Canadians speak a combination of both English (American) and English (British).

The differences between the two versions appear in pronunciation, spelling and vocabulary. The vocabulary differences occur

• as false homonyms (the same word having separate meanings)
• as synonyms (the same object or concept having different words in the two languages).

Rosetta Stone teaches you to distinguish between these words through context.
