Report Learning British English in English Language | Discussion Posted December 12, 2014 The above post pretty much sums up the differences between US and British English. In practice, there are not really any communication difficulties between British and American speakers of English, except for speakers with very strong accents and regional dialects (e.g. Scottish, Geordie), but people can usually moderate their accents to be understood. As a non-native speaker there are only a few vocabulary differences that can cause potential problems:Rubber in British English means an eraser as found on a pencil. In US English it means a condom.Bum in US English means a hobo. In British English it means what you sit on.Fanny in US English means what you sit on. In British English it means, er... something only females have.Fag in British English means cigarette. In US English it's a term of abuse.There are probably others if anyone else wants to chip in.
