kosteikoille

Kosteikoille is the allative form of the Finnish noun kosteikko, meaning a wetland, such as a marsh, swamp or bog. In Finnish grammar, the allative case marks movement toward a place, so kosteikoille translates roughly as “to the wetlands” or “towards wetlands.” The corresponding singular forms are kosteikolle (to a wetland) and kosteikkoon (into a wetland). The form kosteikoille is used when referring to multiple wetlands or when speaking of wetlands as a destination in a general sense.

Usage and context

Kosteikoille appears in geographic descriptions, field guides, nature writing and conservation texts to indicate direction toward wetland areas. Examples include phrases like retki kosteikoille (a trip to the wetlands) or käydä kosteikoille (to go to the wetlands). The term also occurs in place-name descriptions and environmental planning documents when discussing access or movement to wetland sites.

Ecology and grouping

Kosteikko refers to a broad category of wetland ecosystems, including marshes, swamps and bogs, characterized by saturated soils and specialized vegetation. Wetlands play key ecological roles, such as supporting biodiversity, purifying water, mitigating floods and storing carbon. While kosteikko denotes the ecosystem, kosteikoille emphasizes the directional aspect of approaching or moving toward those areas.

Etymology

The word combines kosteikko with the allative suffix -lle, and in plural form yields kosteikoille. The related illative form for entering a wetland is kosteikkoon.
