riittiset

Riittiset is a Finnish adjective meaning adequate or sufficient when describing a plural noun. It is used to indicate that a set of resources, information, or conditions meets the required level. The form is the nominative plural of the adjective riittäinen/riittinen (derived from the verb riittää, “to be enough”), and it agrees with the noun it modifies in number and case.

In practice, riittiset appears in many formal or planning contexts. Common phrases include riittiset varat (adequate funds), riittiset tiedot (adequate information), and riittiset perusteet (adequate grounds). The word helps distinguish items that meet the necessary criteria from those that do not.

Grammar and usage notes: as an -inen type adjective, riittiset inflects like other adjectives of this class. It appears in different cases and numbers to match the noun, for example riittäviä varoja in the partitive plural or riittäisinä perusteina in other constructions. The sense is generally neutral and formal, suitable for reporting, budgeting, and decision-making contexts.

Etymology and related forms: riittiset comes from the verb riittää, with the typical -inen adjective-forming suffix. The related adjective riittävä is often used in singular or more general contexts, while riittiset specifically marks plurality.
