Yes, you distilled the essence of it into those two sentences.benjamiinn wrote:OK I see =),sorry i didnt understand everything , but so it's very important to learn what cases go together with the verbs?
i dont know how i would do that hmm, i guess it comes quite naturally when i study sentences right?
It's not entirely up to the verb. For instance:
Hän meni Kinnulaan. He went to Kinnula.
Hän meni Toholammille. He went to Toholampi.
It depends somewhat on the real-world and grammatical character of the noun.
But in a similar idea you use a different case just because the verb is different:
Hän kävi Kinnulassa. He visited Kinnula (and then returned or continued elsewhere).
Hän kävi Toholammilla. He visited Toholampi (etc.)
Hän kävi jossakin. He visited somewhere.
Hän kävi siellä. He visited there (that place you/someone just mentioned).
That difference between Kinnula/ssa/sta/aan and Toholammi/lla/lta/lle is the most common situation where the nature of the noun complicates what is otherwise a simple verb-requires-case rule. But you can solve that using more examples.
Hän kävi mökillä. He visited the cottage (and its environs, from Helsinki).
Hän nousi ja kävi mökissä. He (was sitting in the yard at a cottage and) rose and went into the cottage and came back out.
So you can think of it in terms of meaning or you can just learn the right reflexes. Nowadays I think the reflexes are better, but thinking about differences in meaning sometimes makes it easier to learn the reflexes.
I lean toward the idea of short sentences that illustrate one idea at a time until you get advanced. If you work on longer sentences, you need to pause when you're learning them, break them into pieces that emphasize the different concepts they illustrate, and focus on the concept for a bit. Otherwise you can reach a point where you're just memorizing sounds, and that's not necessarily helpful.
I also think it's important to frequently revisit earlier sample texts you have studied, thinking about the concepts they illustrate. There can be a tendency to just forge ahead, forge ahead, forge ahead in order to feel like you're making progress. But solidity of what you've studied is just as important as forward advancement. You don't just want to know the rules. You want to develop and reinforce the reflexes. You don't stop shooting baskets just because you hit three in a row. (I'm talking basketball here, not a pistol-firing range.)
As I was writing "forge ahead" three times above, because I type so much my fingers twice wrote "forget ahead" by reflex. And "forget ahead" is a pretty good characterization of what happens when you move forward too quickly without revisiting and consolidated what you've already studied.
