Daire

Daire is a Turkish word with several related meanings that depend on context. It can refer to a geometric figure, a residential unit, or an organizational office or department. The specific sense is usually clear from surrounding words, and the term is widely used in everyday language as well as in formal terminology.

In mathematics, daire denotes a circle and, in many contexts, the disk—the set of points at or within a fixed distance from a center. The word is used in geometry and related fields to discuss radius, diameter, and area. In Turkish, çevre tends to be used for the circumference, while daire is used for the circular area, especially when interior points are included.

In daily use, daire most commonly means an apartment or flat. It is a self-contained housing unit within a multi-unit building, and real estate listings often describe a daire by the number of rooms, layout, or size (for example, a 2+1 daire). The term can appear in combinations such as apartman dairesi, but daire alone is widely understood as a living space.

In organizational and governmental language, daire also means an office, bureau, or department. It designates a defined unit within a ministry, company, or institution. Examples include vergi dairesi (tax office) and icra dairesi (executive office). Here, daire conveys administrative or functional responsibilities rather than a physical dwelling.

Overall, daire is a polyvalent Turkish term whose meaning is determined by context: geometry, housing, or administrative units.
