tietosanat
Tietosanat (Finnish for "content words" or "lexical words") is a term used in Finnish linguistics to refer to a broad class of words that convey substantial semantic content and belong to open word classes. They form the core vocabulary that can describe objects, properties, actions, quantities and circumstances. Common examples include nouns (substantiivit), adjectives (adjektiivit), verbs (verbit), numerals (lukusanat) and adverbs (adverbit). These words are distinguished from function words, such as conjunctions, prepositions and determiners, which primarily serve grammatical functions and tend to form closed classes.
