secção

Secção is a noun in Portuguese that denotes a part or subdivision of a larger whole. The term derives from Latin sectio and is closely related to the idea of cutting or separating a unit into defined parts. In everyday use, secção (or seção, depending on orthography) refers to a portion such as a section of a book, a section within an organization, or a subdivision of a municipal or administrative body.

In documents and organizations, secção is commonly employed to name a specific subdivision or department, for example a “Secção de Contabilidade” or a “Secção de Polícia.” It can also appear in legal or bureaucratic contexts to designate a distinct portion of a law, regulation, or statistical division. In cadastral and land contexts, the word may describe a defined tract or section of land within a larger estate or district.

In science and medicine, secção is used to describe the act or result of cutting a specimen to reveal its interior structure. Phrases such as “secção transversal” (cross-section) or “secção histológica” (histological section) are common, particularly in anatomy and biology. In mathematics and geometry, the related term “seção” is used to refer to a section of a geometric object or a fiber bundle, representing a different formal sense of division.

Overall, secção functions as a versatile term for any clearly delimitable part of a larger entity, with specialized uses in documentation, administration, science, and mathematics.
