In 1834, the book "Teikin Orai Guchusho" (Commentary of Teikin Orai), each letter was broken down into several paragraphs and each paragraph had a let-in note that contained both kanji and kana with all kanji accompanied by furigana, always closing with a section on 'sentence meaning' that summarized the whole paragraph.
1834年『庭訓往来具注鈔』という本では、一通の手紙文を数段にわけ、段ごとに割注（漢字かな交じり文・総ふりがな付き）を挿入、最後に必ず「文意」の項を設け、この段全般に及ぶ意味を要約している。
