Clavero

Clavero is a surname of Spanish origin. The name is derived from the noun clavo, meaning "nail," with the agent suffix -ero, a common pattern in Spanish that denotes a person associated with a task or trade. As an occupational name, it historically referred to someone who worked with nails or hardware, such as a nailer or metalworker.

Today, Clavero is found among Spanish-speaking populations in Spain and across Latin America, and by migration has spread to other regions. Variants and related surnames can be encountered in genealogical records, reflecting regional pronunciations and historical spellings. In addition to its use as a family name, Clavero may appear in toponyms or in institutional names in areas with Spanish linguistic heritage, though such instances are context-dependent and would require local information to identify.

Clavero is distinct from related words such as clave (key) and clavícula (collarbone) in etymology, but shares the same root clavo "nail" that appears in multiple Spanish terms across trade and daily life.
