vinculo

Vínculo is a noun in Portuguese that denotes a bond, tie, or link between entities. The term derives from Latin vinculum, literally a chain or fastening.

In social and personal terms, it refers to relationships that bind people, such as family bonds (vínculos familiares), friendships, or emotional ties (vínculos afetivos). It is commonly used in sociology, psychology, and everyday language to describe attachments that influence behavior and identity.

In legal and organizational contexts, vínculo often designates a formal relationship that connects a worker to an employer, such as a vínculo empregatício or a vínculo de emprego under labor law. It implies rights and obligations and is a central concept in labor regulations in countries like Brazil.

In science, the word appears in expressions such as vínculo químico to denote a chemical bond between atoms, and more broadly to describe connections in biology, physics, or networks.

In information technology, vínculos can be used to refer to a link or connection between digital objects, though hiperlink or link are often preferred depending on the region and context.

Related terms include vínculo familiar, vínculo emocional, vínculo empregatício, and hipervínculo.
