The particle が is different from は. は tells you the main topic. This is often something you already know. が points out the subject of the sentence. This is often new information. It can also show something specific. For example, 'I like cats' uses が for 'cats'. This shows what you specifically like. 'Cats are cute' uses は for 'cats'. This is a general idea about cats.
Watch out: When you ask "who," "what," or "where," you must use "ga." For example, say "Who is coming?" Do not use "wa" with these words. "Ga" shows you are asking for new information.
Don't use this when you want to say "I understand Japanese." You should say "日本語がわかります" not "日本語をわかります." Some words need が. These are words about what you can do. Like 'can do' or 'understand'. They are also words about what you like or dislike. Like 'like' or 'good at'. Words about if something exists also use が. Like 'there is'. Words about what you want use が too. Like 'want something'.
Use this when you want to connect two sentences. It means 'but' or 'and'. It shows a contrast or adds more information. You will see it between two full ideas.
