Finnish Grammar - Verb Forms

Verb Forms

Finnish verbs are usually divided into seven groups depending on the stem type. All seven types have the same set of endings, but the stems undergo (slightly) different changes when inflected.

There are very few irregular verbs in Finnish. In fact, only 'olla' = 'to be' has two irregular forms on "is" and ovat "are (pl.)"; other forms follow from the stem ole–/ol–; e.g. olet ← ole+t "you are", olkoon ← ol+koon "let it be". A handful of verbs, including 'nähdä' = 'to see', 'tehdä' = 'to do/make', and 'juosta' = 'to run' have rare consonant mutation patterns which are not derivable from the infinitive.

Finnish does not have a separate verb for possession. Possession is indicated in other ways, mainly by genitives and existential clauses. For animate possessors, the adessive case is used with 'olla', for example 'koiralla on häntä' = 'the dog has a tail' - literally 'on the dog is a tail', or in English grammar, "There is a tail on the dog". This is similar to Irish and Welsh forms such as "There is a hunger on me".
