Questions & Answers about Isä hakkaa polttopuita kirveellä.
The dictionary form of the word for axe is kirves. Why does it change to kirvee- before adding the Adessive ending?
Words ending in -es, like kirves, belong to a specific word type. When adding most grammatical endings, the -es turns into a long -ee- stem. Then, we add the Adessive ending -llä to express the tool being used to perform the action, which gives us kirveellä.
Why does the Adessive ending on kirveellä use an ä instead of an a?
This happens because of vowel harmony. The stem kirvee- contains only the front vowels i and e. Since there are no back vowels (a, o, or u) anywhere in the word, the grammatical ending must use the front vowel variant -llä instead of -lla.
