sanaluokkiin

Sanaluokkiin is the illative plural form of the Finnish noun sanaluokka, which translates roughly as "word class" or "part of speech." In Finnish grammar, sanaluokka refers to a category of words defined by their syntactic and morphological properties, such as nouns, verbs, adjectives, pronouns, numerals, adverbs, conjunctions, particles, and interjections. The term is used when describing membership of words in these categories, particularly in linguistic explanations or educational contexts.

The illative case in Finnish denotes direction or movement into something, and in the plural the suffix -iin is used. Accordingly, sanaluokka becomes sanaluokkiin in the illative plural. For contrast, the singular illative is sanaluokkaan. The phrase sanaluokkiin kuuluvat means "belong to the word classes" and is common in descriptions of Finnish grammar, indicating that certain words fall within specific grammatical categories.

In practice, discussions of sanaluokkiin appear in grammar explanations, dictionaries, and language-teaching materials that outline which words belong to which word classes and how those classes behave in sentences. While different Finnish grammars may enumerate sanaluokat with slight variation, the core idea remains: words are grouped into categories that influence their form and function in communication.
