Finnish Word Explorer

Finnish is a highly inflected language — a single noun can appear in dozens of forms depending on case, number, and possessive suffix, while verbs change across tenses, moods, voices, and persons. For learners, seeing why a form looks the way it does is often more valuable than just seeing a translation.

Finnish Word Explorer lets you type any Finnish word — a dictionary form, an inflected noun, a conjugated verb — and immediately see its grammatical breakdown: what part of speech it is, which KOTUS inflection paradigm it belongs to, and exactly which suffix or stem change turns the base form into the form you typed.

• 🔍 Search for any inflected form — kalassa, puhun, kauniissa — and see the grammatical analysis instantly.
• 🎨 Colour-coded character-level diffs highlight exactly which letters are the stem, which have changed (consonant gradation), and which are the inflectional suffix.
• 📋 Navigate to a word's full inflection paradigm to see every case or conjugated form in a structured table, with each form clickable.
• 🏷️ Part-of-speech badges cover noun, verb, adjective, proper noun, adverb, and more.
• 📱 Designed to be fast and fully usable on mobile — no app install required.
