Hello!
I cannot introduce myself in Japanese yet, so I'm not going to try. I've been studying Japanese for about 3 weeks on various (free) resources. Right now my favorite resource is
https://www.tofugu.com/learn-japanese/. I've learned Hiragana, and am starting Katakana now. But I feel reassured that I can now ask someone about how to break down sentences and stuff (the grammar and syntax look really complicated).
Ah, tofugu. I personally don't use it but I would recommend not to use it as the only source of learning Japanese. (Of course I already given you stuff so yeah, don't need to branch into that right now.)
So you want to start learning how to form sentences? For now, you are going to learn some from me that would make you already miles ahead, but at the same time being able to understand how Japanese syntax works. Keep in mind, do not believe what sites tell you that Japanese is SUBJECT, OBJECT, VERB. This will come as a shock later when you see Japanese using verbs at the beginning, and objects at the end of things. But lets not go INTO that yet, it's ways too advance and you must have a understanding of verb usage before diving into this.
Right now, let's just focus on the baby steps, and get on with it. Romaji will be excluded because it is a bad habit to be reading it instead of actual Japanese characters.
These words will be important right now: わたし, こんにちは, and です.
In Japan, pronouns are stated in levels of kindness and gender you are. And with our hellos and welcomes, they work similar and politeness should be taken granted on what part of the day, and first meeting. For こんにちは should be used in the morning, or greeting if you aren't sure what time of day it is. Japanese often will welcome it either way, and it is the safest bet.
First, the most easiest thing to know as a sentence is: わたしはフォルテです.
"I am Forte", and it is subject, object (me), and です tossed at the end as a ending marker to the sentence. Desu, and yeah, using romaji here, kill me. Take desu as a cherry on top to make a sentence very polite, and later you will end up learning the ones that are NOT polite. If you ever watch Dragon Ball Z in Japanese, Goku will say a very common word: "そうだ！”
That is "That's right!" in informal, causal Japanese. Do not use that in first time conversations, it comes off as rude. As you advance more, you can take off the ending to such and just have a sentence without, but come off as blunt.
Earlier in one of my post, I put this as an example for greetings. Textbooks do avoid this stupidly and it is very important to learn early on, " ともします".
Add that after your name when you greet yourself for the first time. It's very, very formal and makes you sound very Japanese, and polite.
Let me run down on two particles to get into creating your first sentence structures so you will memorize them while learning both hiragana, and katakana. は, が, and の.
は is instead the 'ha' hiragana when being used. It comes after konnichiwa, which you spot the wa here. It's just already attached and ready to use. It is a topic starter, it indicates there is a new topic, something not aware to the user. Then comes it's controversial cousin!
が is a active topic, the user is aware of this subject and ga is used to indicate that. This one will be a problem for beginners since it can change roles accordingly and act like a annoying itch where you can't scratch. They do however come after the wa particle, and after pointing directions or actions.
の is my most favorite particle, and the easiest to get the hang of. It is a plural, and his, mine, and theres, whatever. It is a very big topic marker and will present you a open world once it is learned.
わたしのいぬ、わたしのねこ、わたしのくるま
And for the ga particle...
これが私の車で、私はこれを運転します.
Pay attention to the context of the ga being used, it's used for action and for the topic already being known. The listener knows that most everyone uses a car, and the topic becomes wa to know that I am telling the listener something new, I drove it.
So that is all I am going to teach for now, it is a lot. If you have any other questions, feel free to ask me.
