Länsipuoli

Länsipuoli is a Finnish term meaning the western side or western part of something. It is formed from the word länsi, meaning west, and puoli, meaning side or half. The expression is a geographic and descriptive compound used across Finnish language to indicate position relative to a reference point, such as a building, plot, river, or city center.

The term is common in everyday language, real estate descriptions, and planning documents. In maps, signs, and property adverts, länsipuoli may refer to the part of a building or property that faces west or lies on the western side of a block. It can describe the western wing of a house, the western-facing façade, or the portion of a district located to the west of a chosen reference line. The exact meaning depends on context and the referenced reference point, making it a relative rather than an absolute designation.

Länsipuoli is not typically an official administrative unit. Municipalities usually designate areas by official names and borders, while länsipuoli functions as a descriptive label used in communication, navigation, and planning to distinguish western parts from eastern ones. Related terms includeitäpuoli (east side), pohjoispuoli (north side), and eteläpuoli (south side), which form part of the same system of directional expressions in Finnish. In practice, usage emphasizes orientation and practicality rather than formal geography.
