Sentence shape and noun sentences

Not started · 0%

Japanese sentence shape

Pattern: Topic + information + predicate

Meaning: Japanese usually places the main predicate at the end, so wait for the final chunk before deciding what the sentence does.

Build it: Read particles as signposts, then hold the earlier chunks in place until the final predicate arrives.

Common mistake: Do not force English word order or assume the first noun is the object.

Examples

Tap a dotted word for its meaning.

  1. は 本ほんを 読みよみます。I read a book.
  2. 今日きょうは 家うち 。Today I study at home.

How practice works

Practice that grows with you

Work through form choices, sentence building, and grammar in context. Every answer includes an explanation and a retry, and later rounds bring back patterns that still need work.

Learn the pattern

Review the meaning, formation, common mistake, and two translated examples.

Correct each exercise

Retry immediately and read why the answer works before moving on.

Keep it fresh

Come back for new examples and quick reminders instead of stopping after one pass.
