planul

Planul is a Romanian noun meaning the plan, usually used as the definite form of plan. It is masculine and appears in two main senses: a proposed course of action or a drawing, schematic layout, or program to be followed; and in geometry, the plane, a two‑dimensional surface.

Etymology and usage context: The word planul derives from the French word plan, which itself comes from Latin planus. In everyday language, planul refers to a concrete or abstract arrangement, for example planul de afaceri (business plan), planul de acțiune (action plan), or planul urban (urban plan). In mathematics and related fields, planul denotes the geometric plane, as in planul euclidian (the Euclidean plane).

Grammar and forms: Planul follows the typical masculine noun pattern in Romanian, with the plural being planuri and the definite plural planurile. The definite form is used when referring to a specific plan that is known from context, while the indefinite form un plan is used for a plan mentioned without specification.

Relation to related terms: Planul is often contrasted with proiect (project) and schemă or diagramă (scheme or diagram) in Romanian. Proiect usually emphasizes a concrete product or deliverable, while planul emphasizes a strategic, methodological, or organizing framework, whether for business, policy, or architecture. The term is widely used across sectors such as business, urban planning, architecture, and education.
