What is the difference between dialect and language?

Dialect and language are often times interchanged by people. In order to separate them, you might want to consider how dictionary define the two. Language, it says, is a mass noun that describes “the method of human communication, either spoken or written, consisting of the use of words in a structured and conventional way.” While dialect is defined as “a particular form of a language which is peculiar to a specific region or social group.” To cut it short, dialect is a variety of a language.
