eräiset

Eräiset is a Finnish word used to mean "certain" or "some" when referring to a subset of people or things. It functions as an attributive adjective or a pronominal determiner and is commonly used in ordinary speech and writing to single out unspecified members of a group.

Grammatically, eräiset corresponds to the plural form used with countable nouns (for example, eräiset ihmiset — "certain people"). It is related to the pronoun/adjective eräs ("a certain") and can be used in contexts where English uses "some," "certain," or "particular." Synonyms and near-equivalents include tietyt and jotkut, though each carries slightly different nuances in emphasis and specificity.

Usage examples:

- Eräiset ihmiset eivät pidä suurista tilaisuuksista. (Certain people do not like large events.)

- Tätä ongelmaa kohtaan eräiset ratkaisut ovat tehokkaampia. (Some solutions to this problem are more effective.)

In style and register, eräiset is standard Finnish and appears across formal and informal contexts. Its precise form and inflection follow regular Finnish adjective morphology when combined with nouns. Cross-linguistically, it corresponds to words such as English "certain" or Swedish "vissa."
