lukuisilla

Lukuisilla is a Finnish adjective form meaning numerous or a large number of something. It is derived from the adjective lukuisa and is used to describe plural nouns when the noun phrase is inflected for a case that requires an -lla/-illä ending, most commonly the adessive. In practice, lukuisilla signals that there are many of the referred items and often adds emphasis to quantity.

The form is widely used in written Finnish and appears in journalism, academic writing, and formal prose, as well as in everyday speech. It tends to convey a sense of breadth or abundance rather than a simple count and is therefore a stylistic tool for foregrounding quantity. Because Finnish adjectives agree with the noun in number and case, lukuisilla will appear with plural nouns in cases that take -lla/-illä (for example, lukuisilla osallistujilla = among/with numerous participants).

Etymology and related forms: lukuisilla comes from lukuisa, meaning numerous. The root luku- is related to number, and the adjective incorporates suffixes that create a family of forms for different cases and numbers. Other common inflected forms of the same root include lukuisat (nominative plural) and lukuisia (partitive plural).
