What does transection mean?
Transection is a rare noun meaning a cut made across an object or structure, especially one intended to reveal its internal organization. It is especially associated with anatomy, biology, geology, and technical illustration, where a transection provides a view perpendicular to the object's surface or length. The word can also refer more broadly to the act of cutting across something. In contemporary writing, however, cross-section and section are usually clearer and more familiar, while transect is often used for a line that crosses a region. Transection is consequently best suited to formal, descriptive, or specialized prose. Its Latin ancestry connects it with words such as section, dissection, and intersection, all of which involve the idea of dividing or making an intersection.
