Japanese grammar terminology and structures
Grammar pattern names, thematic classification and linguistic terminology are shared knowledge in the field and are owned by no one. What is copyrighted is how we explain them and the examples we write.
Our rules for external content
- We do NOT republish copyrighted articles in full, including translations.
- For news, we use only the headline, a short excerpt, and always link back to the original.
- Where we need full Japanese text, we use sources that permit reuse: material published under 政府標準利用規約 (compatible with CC BY 4.0), CC BY-SA content, or works out of copyright.
- For news items, the source is credited on the page itself. For material shared across many pages — stroke-order diagrams, example-sentence corpora — the source and licence are listed in the section below.
External sources and licences
- Kanji stroke-order diagrams: KanjiVG (kanjivg.tagaini.net), © Ulrich Apel and contributors, licensed CC BY-SA 3.0. We host a copy of 1,227 characters on our own server; the stroke data is unchanged, only unused metadata was removed.
- Stroke-order diagrams for the kana — 46 hiragana and 71 katakana (including 25 voiced and semi-voiced characters): also from KanjiVG, under the same CC BY-SA 3.0 licence, hosted on our own server and processed exactly like the kanji set above.
- Japanese example sentences: mostly from the Tanaka Corpus / Tatoeba (tatoeba.org), Public Domain / CC BY 2.0 FR. Translations into Vietnamese and the other languages are our own.
