Jäisiä

Jäisiä is the plural partitive form of the Finnish adjective jäinen, meaning icy or frozen. It is used to describe multiple objects that are icy or coated with ice, when the noun is in partitive case or when the indefiniteness of the quantity is emphasized.

Morphology and usage are straightforward in Finnish. The base adjective jäinen takes the partitive plural ending -iä, yielding jäisiä. It agrees with the noun it describes in number and case, for example jäisiä vesiä (icy waters) or jäisiä kiviä (icy stones). Because partitive is used to indicate an indefinite amount or non-complete quantity, jäisiä is common in expressions about ice-related conditions or frozen matter without specifying a precise count.

Common contexts include weather, nature, and observations of frozen objects. Examples of collocations include jäisiä vesiä, jäisiä kappaleita, tai jäisiä paloja. The form is especially frequent in descriptive prose and in discussions of lakes, streams, or winter scenes where ice is present but not quantified.

Etymology and related forms: jäinen is formed from the noun jää (ice) with the suffix -inen, producing “icy.” The word’s inflected forms follow standard Finnish adjective patterns; related forms include jäinen (nominative singular) and jäisiä (partitive plural). Semantically related terms include jäätynyt (frozen, in a completed sense) and jäätikkö (glacier).
