  Everyone knows that you can study the English language for years and still not understand a native speaker of English.

Well, here’s a secret for you: a lot of British people can’t understand each other either! Apart from the different regional accents across the country, language can also differ (不同) among age groups. The words and pronunciations used by young Britons can be very different to those used by adults. This is called “yoof” culture.

The word “yoof” is a slang (俚语) spelling of “youth”. Some people consider “yoof” to be a negative (消极的) term, since its pronunciation is easier than “youth”. Other people see the term as positive, because it describes how young people are creating their own language, concepts (观念) and identity.

When parents find it difficult to understand their children, the children can say more things without the censorship (审查) of their parents. In this way, young people are starting to find freedom, independence and self-expression.

They are creating a “yoof culture”. It is impossible to come up with a complete list of words used by yoof. By the time the list was completed, it would be out of date. New words come and go like fashions.
