Questions & Answers about Lupasin kirjoittaa kommentin blogiin.
The verb for "to promise" is luvata. Why does it change to lupasin with a p here?
Luvata is a Type 4 verb. A tricky feature of Type 4 verbs is that their basic infinitive form uses the weak consonant grade (here, v), but their conjugated forms flip to the strong grade (here, p). That is why luvata becomes lupasin (I promised) or lupaan (I promise).
This lesson focuses on cognitive verbs taking the elative case (-sta/-stä). Why is there no elative in this sentence?
The verb luvata involves communication, but it behaves differently than verbs like kertoa (to tell) or ajatella (to think). Instead of talking about something (which takes the elative), you are promising to do an action. To express this, you just attach the basic infinitive of the action verb, which is kirjoittaa here.
Why is it blogiin (illative, "into the blog") instead of blogilla or blogissa?
In English you write a comment on a blog, but in Finnish, the verb kirjoittaa (to write) is often treated as a directional verb. You are putting text into a destination, so it requires the illative case (blogiin).
Why does the word kommentti end with an -n here?
