mononym

This term is primarily used in linguistic, sociological, or pop-culture contexts to describe the branding of an individual. It carries a connotation of prestige, uniqueness, or extreme fame, as the ability to be recognized by a single name usually implies a level of global prominence that renders a surname redundant.

While the word is a technical descriptor, it is frequently used in discussions about celebrity identity and stage names. It is distinct from a nickname or a pseudonym, as it specifically refers to the structural composition of the name—the absence of a second name—rather than the act of renaming.
