rännid
Rännid is a term that can refer to several different things depending on the context, though it most commonly relates to drainage systems. In a general sense, "rännid" is the Finnish word for gutters or drains, specifically those used to channel rainwater away from buildings or paved areas. These structures are typically long, narrow channels designed to collect and direct water, preventing it from accumulating and causing damage.
Architecturally, rännid are an integral part of a building's exterior, often found along the eaves of roofs.
Beyond buildings, the term can also apply to engineered drainage channels in landscapes, such as along roadsides
