In Basil Bernstein's theory, the restricted code was an example of the speech patterns used by the working class. He stated that this type of code allows strong bonds between group members, who tend to behave largely on the basis of distinctions such as 'male', 'female', 'older', and 'younger'. This social group also uses language in a way that brings unity between people, and members often do not need to be explicit about meaning, as their shared knowledge and common understanding often bring them together in a way that other social language groups do not experience. The difference with the restricted code is the emphasis on 'we' as a social group, which fosters greater solidarity than an emphasis on 'I'.
