kasteluun

Kasteluun is a Finnish linguistic term referring to the illative case form of the noun kastelu, which means watering or irrigation. In Finnish, illative forms are used to indicate direction toward something or to express a purpose, and kasteluun is commonly encountered in technical or agricultural texts to denote water that is intended for irrigation or the act of applying water to plants.

Etymology and form: Kastelu is derived from the verb kastella, meaning to water. The illative form kasteluun combines this root with the illative suffix -uun, yielding a phrase equivalent to “into irrigation” or “for irrigation” depending on context. In practice, kasteluun appears in constructions that specify water or resources designated for irrigation, or actions directed at irrigation.

Usage and context: Kasteluun is primarily found in agricultural, horticultural, or landscaping contexts. It can appear in phrases such as kasteluun tarkoitettu vesi (water intended for irrigation) or kasteluun käytettävä vesi (water to be used for irrigation). Because illative forms interact with word order and modifiers, kasteluun often accompanies adjectives, nouns, or participial phrases that clarify purpose or destination.

Related terms: Kastelu (watering/irrigation), kastelupäätökset (irrigation decisions), kastelumenetelmät (irrigation methods). The term is generally not used in everyday conversation, but may be encountered in manuals, guidelines, and technical documentation concerned with plant care and irrigation planning.
