Explanation of particles and such
One of the problems I noticed when using Duolingo's version of Japanese is that there is seemingly no explanation of particles and other oddities like them. An example of this is how Ha(は) is said wa in certain situations and how it is used as a topic particle. As a person who has studied some Japanese I already understand this but for a beginning learner they would not know this due to the lack of an explanation. I know that the the Japanese program is still in the making but this is something I believe would be very helpful to new students.
Came here to say the same thing. Unlike the German language, which did a better (not great but better) job at explaining particles, the Japanese one just assumed you know it. For the longest time, I couldn't understand why I needed to use は instead of わ because, as far as I was taught in the app, they were different. I just kept getting it wrong and never knew why because the app never bothered to say "Hey, FYI, it's different and here is why."
I agree - to be honest I still don't really know what particles are and what they mean. I just go with what duo teaches me and memorise it. If anyone is willing to go through the basics, it'd be greatly appreciated :D Or, alternatively, if you have any links to a site or video that'd help, I'd love that as well.
I did some research and was able to find this: https://8020japanese.com/japanese-sentence-structure/
[Topic] + は (WA) + [Verb] [Object] + を (WO) + [Verb] [Time] + に (NI) + [Verb] [Location] + で (DE) + [Verb]
は (WA) indicates topic of sentence か (KA) indicates question, placed at end of sentence の (NO) indicates possession
