Dialect
【正确答案】：A dialect is a variety of a language which is defined according to the characteristics of the user of the language, such as region, social class, age, sex, ethnic background, and so on. A dialect is often associated with a particular accent, a particular way of speaking which tells the listener something about the speaker's background. Dialects can be classified into regional dialect and social dialect, but apart from these two broad categories, there are also dialectal varieties called idiolect and temporal dialect.
