Finnish Verb Type 1 includes verbs whose infinitive ends in two vowels (like puhua, antaa, tietää). They’re the largest and most regular verb group, making them ideal for beginners. Remove the final -a/-ä to get the stem, then add personal endings. Mastering this pattern builds a strong base for everyday Finnish.

Vowel harmony in Finnish is the agreement between vowels within a word, affecting suffixes. Finnish vowels are divided into back (a, o, u), front (ä, ö, y), and neutral (e, i) groups. Words typically use either front or back vowels plus any neutral ones. Endings match the vowel type of the root word. In compound words, the last part determines the harmony. Mastering vowel harmony helps learners form words correctly and understand Finnish sound patterns.
