Input: Read this: As a non-directive and flexible analytical tool, the concept of boundaries helps both to map and to define the changeability and mutability that are characteristic of people's experiences of the self in society. While identity is a volatile, flexible and abstract 'thing', its manifestations and the ways in which it is exercised are often open to view. Identity is made evident through the use of markers such as language, dress, behaviour and choice of space, whose effect depends on their recognition by other social beings. Markers help to create the boundaries that define similarities or differences between the marker wearer and the marker perceivers, their effectiveness depends on a shared understanding of their meaning. In a social context, misunderstandings can arise due to a misinterpretation of the significance of specific markers. Equally, an individual can use markers of identity to exert influence on other people without necessarily fulfilling all the criteria that an external observer might typically associate with such an abstract identity.
