seciunile

Seciunile are the Romanian plural form of the term secțiune, used to denote a part, division, or cross-sectional view. The word derives from Latin sectio, through French section, and is employed across several domains to indicate a distinct portion of a whole or the act of cutting to reveal internal features. The standard form with diacritics is secțiunile; seciunile is a common ASCII rendering.

In architecture and engineering, a secțiune or cross-section is a drawing or vertical cut that reveals interior layout, structure, materials, and dimensions. Such views are used in design, construction documentation, and structural analysis.

In mathematics and geometry, secțiune denotes the intersection of a solid with a plane, producing a cross-section. Conic sections, or secțiuni conice, include ellipse, parabola, and hyperbola. Planar sections are used in analytic geometry to study shapes and volumes.

In publishing and documents, secțiune refers to a named part of a text, such as Secțiunea 1 or Secțiunea a doua, helping organize content and navigation.

In surveying and cartography, secțiuni can denote subdivisions of land or grid units used in maps and cadastral records, aiding reference and administration of parcels.

The meaning of seciunile is therefore context-dependent, spanning technical drawings, geometry, textual structure, and geographic delineation.
