välkkyvään

Välkkyvän is the genitive singular inflection of the Finnish adjective välkkyvä, which means glittering, sparkling, or shimmering. In Finnish grammar, adjectives agree with the noun they modify in case and number, so välkkyvän appears when the noun is in the genitive singular. For example, in the phrase välkkyvän valon kajastus, the adjective describes the glow of the glittering light.

The base form välkkyvä is formed from the root välkky- “to glitter” with the participial suffix -vä, indicating a continuing state or quality. The genitive singular ending -n attaches to the stem, producing välkkyvän. This form is used regardless of gender, number (singular), or other noun forms, provided the modified noun is in genitive singular.

Usage of välkkyvän is common in descriptive prose and poetry to convey vivid imagery of surfaces or phenomena that flash or shimmer. It frequently appears in descriptions of natural light, reflections, or artificial illumination, such as stars, water, metal, or glass, where the emphasis is on a glittering or fleeting brightness. While välkkyvän specifically marks the genitive singular, the corresponding adjective forms adjust to other noun cases and numbers as needed (e.g., nominative välkkyvä, partitive välkkyvää).

Etymologically, the term reflects the Finnish tendency to form descriptive adjectives from verb roots related to light and appearance, yielding concise, imagery-rich expressions.
