kristalls

Kristalls is the genitive singular form of the German noun Kristall, meaning crystal. It is used to indicate possession or a relationship to a crystal, as in die Farbe des Kristalls (the color of the crystal) or die Struktur des Kristalls (the structure of the crystal). The standard nominative plural form is Kristalle.

Etymology and form: Kristall derives from Greek krustallos, via Latin crystallum, into German. The genitive singular Kristalls is formed by adding -s to the stem Kristall, following ordinary German possessive inflection rules. This form is common in written German when describing attributes or features belonging to a single crystal.

Usage: In scientific and technical writing, Kristalls appears in phrases that require a genitive singular reference to a specific crystal. For example, "Die Eigenschaften des Kristalls hängen von seiner Ausrichtung ab" (The properties of the crystal depend on its orientation). It is not a plural form; Kristalle is the standard nominative plural, while the genitive singular is Kristalls.
