effektens

Effektens is a grammatical form in Swedish, representing the definite genitive of the noun effekt (the effect). It is used to indicate possession or association, as in phrases like the effect's duration or the effect's causes. The form is created by taking the definite singular effekten (the effect) and adding the genitive ending -s, yielding effektens. For the plural, the corresponding genitive is effekternas (the effects' or of the effects).

In practice, effektens appears in technical, scientific, and descriptive writing to link attributes to a specific effect. Examples include effektens varaktighet (the duration of the effect) and effektens intensitet (the intensity of the effect). In more everyday language, speakers may also express possession using the preposition av, as in effekten av något, rather than the genitive form.

Etymology and related forms: effekt comes from Latin effectus, via French effet and English effect. The genitive form effektens is part of standard Swedish grammar for definite nouns and mirrors similar possessive constructions in related Scandinavian languages.

Notes: The Swedish language also uses other constructions to express attribution, such as av plus a noun phrase, depending on style and emphasis. The plural genitive of effekt, effekter, follows the same general pattern, with the definite plural effekterna and its genitive effekternas.
