A social marker is a discernible sign that gives a clue to a group identity of the person with the marker.[1] It is frequently used by members of elite to indicate their dominant position through appearance, speech, dress, choice of food, and rituals of socializing,[2] so called class markers.[3]
The markers delimit the boundaries between the social groups, connecting a person to "in-group" people like them and at the same time separating from the "out-group" ones (unlike others).[4]
