Japanese sentence basics

Build polite noun sentences, choose particles from context, connect nouns with の, and ask questions that request a clear piece of information.

Build a predicate before adding complexity

Begin with noun sentences using です. Learn to identify yourself or an object, deny an incorrect category with a complete negative, and omit a topic only when it remains clear. These small sentences establish a reliable structure for the later lessons.

Next compare は and が in specified conversations. A topic description, an identifying answer, a basic existence report, and a preference expression have different jobs. The lesson deliberately avoids a universal old information versus new information rule. Context and the predicate matter more than an isolated English translation.

Connect nouns, then ask for what is missing

The possession lesson teaches the inner phrase before the full sentence. 私の本 names my book; これは私の本です identifies an object as that book. The difference prevents a phrase from being mistaken for a complete statement of having something.

The question lesson then changes one known part of a statement into an information gap. A supplied category plus か asks whether the identification is correct. 何 requests the category itself, while だれの requests an owner. Practice deciding what you need to know before choosing a question word.

Move from an explanation to your own exchange

Each lesson contains two worked examples, production tasks, corrections, and explained answer choices. Read one modeled decision, attempt the guided decision, then make an example without visible choices. The questions provide feedback on that understanding rather than serving as the first exposure to the rule.

Finish with the conversation ordering activity in the question lesson. The speakers identify an object and then its owner, so each turn changes what the next speaker knows. After arranging the lines, reconstruct the exchange with a different object. That small substitution tests whether you understand the sentence relationships rather than only remembering card positions.
