Nopeakasvuisten

Nopeakasvuisten is a Finnish grammatical form rather than a standalone concept. It is the genitive plural of the adjective nopeakasvuinen, meaning “fast-growing” or “rapidly growing.” The form is used when the noun it describes is in the genitive plural, a common situation in scientific and descriptive prose.

In practice, nopeakasvuisten appears in phrases that refer to multiple fast-growing entities in genitive plural. For example, nopeakasvuisten kasvien ominaisuudet means “the characteristics of fast-growing plants,” and nopeakasvuisten lajien kasvua can refer to the growth of fast-growing species. The construction reflects Finnish agreement rules: when the noun is genitive plural, the adjective also takes a genitive plural ending, resulting in nopeakasvuisten.

Morphology and formation: the base is nopeakasvuinen, formed from nopea (fast) + kasvu (growth) with the -inen suffix to create an attributive adjective. The genitive plural ending -isten is then applied when the noun it modifies is in genitive plural.

Usage and scope: nopeakasvuisten is most common in academic, agronomic, botanical, and ecological contexts, where there is a need to characterize multiple organisms, cultivars, or populations by their rapid growth. It can also appear in broader writing to emphasize rapid development in various fast-growing subjects.
