Why do some cultures treat names as powerful or taboo?

In the context of the philosophy of language and sociology, the treatment of names as powerful or taboo is deeply rooted in the concept of taboo, which functions as a system of social control to protect individuals and communities from perceived dangers.1

Names are often viewed as powerful because they are not merely labels but are seen as extensions of an individual’s identity or essence. In many cultures, a name is considered a locus of sacred power or mana. Consequently, treating a name as taboo—such as prohibiting the use of a person’s name or restricting who may speak it—serves to prevent the "defilement" of that sacred power by ordinary or inappropriate use.1

This practice aligns with the broader understanding that taboos relate to objects and actions significant to the social order. When a name is linked to a deity, a chief, or a significant life event, it is often bestowed with great solemnity. By restricting the use of such names, a society reinforces the boundary between the sacred and the profane, ensuring that the ritual security of the community is maintained.12
