Questions & Answers about Kävelen metsän läpi.
What does Kävelen tell me about the subject and tense? Why is minä not written?
Kävelen is the 1st person singular present tense of kävellä (to walk).
- kävele- = verb stem
- -n = ending for I (1st person singular)
So kävelen literally means I walk / I am walking.
Because Finnish verb endings already show the person, the subject pronoun minä (I) is usually left out unless you want to emphasize it:
- Kävelen metsän läpi. = I walk through the forest.
- Minä kävelen metsän läpi. = I walk through the forest (not someone else, or stronger emphasis on “I”).
Why is it metsän and not metsä? What case is this?
The base form is metsä (a forest). In the sentence it appears as metsän, which is the genitive singular form.
The postposition läpi (through) requires the noun before it to be in the genitive:
- metsä → metsän läpi = through the forest
- talo (house) → talon läpi = through the house
- kaupunki (city) → kaupungin läpi = through the city
So metsän is there because läpi governs the genitive case.
