uimaaltaista

Uimaaltaista is the elative plural form of the Finnish noun uima-allas, meaning swimming pool. It is used to indicate origin or source and translates to “from the swimming pools” in English. The form appears in contexts where multiple pools are the source of something, such as water or wastewater.

In Finnish, the elative case expresses origin and is formed with the suffix -sta/-stä. For the compound noun uima-allas, the plural elative form is typically written as uima-altaista. The corresponding singular elative is uima-altaasta. Because uima-allas is a hyphenated compound, its inflected forms generally reflect that hyphenation in standard orthography.

Examples of use include environmental or utility contexts, where information is given about sources of water, contaminants, or supply. For instance, “Jätevedet olivat peräisin uima-altaista” means “The wastewater originated from the swimming pools,” and “Vesi kerätään uima-altaista” means “The water is collected from the swimming pools.” Such constructions illustrate how the elative plural functions in practical Finnish.
