tetos

Tetos is the plural form of the Portuguese noun teto, meaning roof or ceiling. In Portuguese, teto can refer to the exterior roof of a building as well as the interior ceiling. Tetos, used in the plural, describes multiple roofs or ceilings and is common in architectural or construction contexts. For example, discussions about a housing project might mention the tetos of several houses, or refer to interior design considerations for different rooms’ tetos. The term is used in both Brazilian Portuguese and European Portuguese, with the distinction between exterior and interior surfaces usually made clear by context or accompanying descriptors such as teto externo (exterior roof) or teto da sala (ceiling of the living room).

Etymology and related terms: The word teto is derived from Latin tectum, meaning roof or covering. This root is shared with cognate terms in other Romance languages, such as Spanish techo and French toit, which reflect the same origin and semantics.

Other uses: Outside Portuguese-language contexts, tetos is not a standard English word. It may appear as a proper noun or surname, or in discussions that reference Portuguese-speaking regions or materials. As a loanword, its recognition depends on the surrounding linguistic context.
