So I'm just starting out with the Japanese tree, I've gotten hiragana down and some katakana/kanji, but the grammar is still very confusing to me. I tried reading the light bulb sections for each lesson and that helped a little bit, but a lot of the grammar just doesn't make sense.
For example, for the wa/wo/ka/ga words, I'm not sure when to use them and where to put them. I also don't understand when to use what script (hiragana, katakana, kanji) because there's sometimes a mixture of the three? For the direct object, what does that do, where does it go, and what does it mean? And for some sentences like "I am eating," 'desu' goes at the end but where does eating go? And do you need "wa" for that sentence? The most confusing thing is just the order of everything and what particles go before/after the subjects/objects/verbs.
If anyone could try to explain this to me, it would help me out so much. Thank you!!
I recommend reading this brief introduction to Japanese grammar. It should answer many of your initial questions and give you a better grounding in the basic structure of a Japanese sentence. The section on particles is especially helpful. You can probably skip the verb conjugation at the end. That's a little deep, if you are just starting out.
You will probably still have a lot of questions after reading this "quick and dirty" guide, but hopefully you won't feel quite so lost. Feel free to ask if you don't understand something or want to know a little more. Grammar is one of the tougher aspects of Japanese, but also one of the most important things to learn properly.
