My native language is English, and I'm still studying Japanese. I have many questions about particles.
To start, I know that が and は are both used similarly. が as a topic marker, and は for the topic marker.
However, I still don't fully understand the differences between them. For example...
What would the difference be for these sentences?:
ベンさんは楽しかったです。 ベンさんが楽しかったです。
マリさんは食べました。 マリさんが食べました。
Also, I have a question about に and で. I know that に is usually used to show where you want to go, and で is used in many ways. By means of, at, and because.
But I'm still confused in general what they would be translated as. For example, what's the differences in these sentences?:
箸で食べました。 箸に食べました。
あの場所に行きました。 あの場所で行きました。
I'm sorry if these don't fully make sence. I'm still learning the language.
If I could, let me recommend a book to you. "A beginers dictionary to Japanese grammar".
It's published through the Japan times, I think. It's incredibly useful. I read it as a book, tons of explanations and shows different functions of many particles and structures.
(1) ベンさんは楽しかったです。---> Discribing just a simple fact or thing. Ben had a good time.
(2) ベンさんが楽しかったです。---> Stressing Ben. It was Ben who had a good time. (indirectly suggesting that I am not sure other people had their good times as well.)
(3) 箸で食べました。---> As Hashi is a tool, "で" here means "with this tool". Therefore, the sentence will be "I had it with the chopsticks". If Hashi here should happen to be a name of a place, it goes like "I had it in / at Hashi".
(4) 箸に食べました。---> We don't say like this. "に" is incorrect because Hashi is a tool plus "に" usually means "to somewhere" or "for a certain destination", which is an inappropriate Particle for Hashi.
(5) あの場所に行きました。---> OK. I went that place.
(6) あの場所で行きました。---> We donot say like this. "で" is incorrent because "行きました" suggests a movement of going from one place to another plus "で" usually means "at somewhere", which is an inappropriate Particle for "行きました"(verb).
I donot upset of course.
I just wanted to point out the fact from my experience as a Japanese.
I am not saying you are wrong either, but "ベンさんは楽しかったです。" will be less likely to mean "Ben was funny." than "Ben had a good time", in general. Surely it depends on the situation, as you say.
