sección

Sección is a Spanish noun meaning a part or subdivision of a whole, and it can refer to a division in text, space, or organization. The word comes from Latin sectio, from secare “to cut.” Its usage is broad and context-dependent.

In writing and media, a sección designates a part of a publication or document, such as a chapter, segment of an article, or a department within a newspaper or magazine (for example, the sports sección). It is also used to describe a subdivision within an organization or service, like a sección de ventas or una sección administrativa.

In geometry and science, sección denotes a cross-section: the figure obtained by cutting a solid with a plane or line, as in sección transversal. In biology and medicine, it appears in terms like sección histológica (histological section) or sección anatómica, referring to prepared slices of tissue or anatomical parts.

In administration and institutions, sección refers to a functional unit within a ministry, agency, police corps, or company, often with specific duties and scope. In music, a sección can describe a group of instruments, such as the cuerda sections (string section) of an orchestra.

In cartography and land surveying, sección is a defined parcel or block of land or a division within a map or cadastre. The exact meaning varies by country and field, but it generally implies a deliberate subdivision used for organization, analysis, or control.

Overall, seccion represents a flexible concept of subdivision, with its precise sense determined by disciplinary context.
