How the analyzer breaks down a Japanese sentence
Take 雨が降りそうですね。 The analyzer splits it into 雨 (ame, "rain", a noun), が (ga, the subject marker), 降り (furi, the stem of the verb 降る "to fall"), そう (sou, "it looks like"), です (desu, the polite copula), and ね (ne, a sentence-ending particle that seeks agreement). Together that is "It looks like it is going to rain, doesn't it?"
Seeing each piece, instead of only the translation, is what turns a sentence you can read into grammar you can actually reuse. For every sentence you get the word-by-word breakdown, the particles, verb forms, sentence structure, formality, tense, furigana, and a plain explanation.
Mistakes the analyzer helps you see
- は vs が: は marks the topic (what the sentence is about), が marks the subject (who or what does the action). The analyzer labels each so you can tell them apart.
- を vs が on verbs: it shows which noun is the object and which is the subject.
- Politeness: it detects whether the sentence is casual, polite, or formal from the verb endings.
- Dropped subjects: Japanese often omits the subject, and the explanation makes the implied meaning clear.
