Perusmuotoihin

Perusmuotoihin is a Finnish term that translates to "basic forms" or "root forms." In linguistics, it refers to the uninflected or base form of a word, typically the nominative singular for nouns and adjectives, and the infinitive for verbs. This is the form that dictionaries usually list words under. Understanding perusmuotoihin is crucial for learning Finnish grammar as it serves as the starting point for all other grammatical inflections.

For instance, the noun "talo" (house) is the perusmuoto. From this base form, various cases can be derived, such as "talossa" (in the house) or "taloon" (into the house). Similarly, the verb "puhua" (to speak) is the perusmuoto. Inflected forms like "puhun" (I speak) or "puhui" (he/she spoke) are built upon this infinitive. Recognizing and correctly identifying the perusmuoto of a word is a fundamental step in mastering Finnish morphology and syntax. It simplifies the process of understanding how words change and interact within sentences.
