## What is Perusmuoto?

Perusmuoto helps you recognize Finnish words appeared in any forms.

Finnish words can appear in many forms. A noun, adjective, pronoun, numeral, or verb may look very different from its basic form. Perusmuoto is built for exactly that moment: type the word form you found, discover its lemma, and open a clear card with the related declension or conjugation forms.

Whether you are reading Finnish text, studying grammar, translating a sentence or trying to understand a word you just saw, Perusmuoto gives you a fast way back to the basic form.

Features:

• Find the basic form of Finnish words from inflected forms
• Search nouns, adjectives, pronouns, numerals, and verbs
• Open full declension and conjugation cards
• Compare positive and negative verb forms
• View adjective comparison forms when available
• Use color-coded word classes for quicker recognition
• Choose from modern visual themes
• Adjust text size for comfortable reading
• Use the dictionary offline after subscribing
• Fully autonomous, doesn't require Internet connection

Perusmuoto is especially useful for Finnish learners, readers, translators and anyone who wants to understand how Finnish words are built.
