Two other significant differences involve the "way" that kana are used in general, rather than "which" kana are used. The first is that Chinese characters in classical texts are often fully marked with ruby text ( "Furigana"), especially in old laws and other very important documents. Ruby text is still widely used in modern Japanese, but only for characters with non-standard or ambiguous pronunciations, or sometimes in materials designed for children or foreigners. The second difference is that, especially in legal documents, Katakana were often used in the way that Hiragana are used in modern Japanese, to write out adjective and verb inflections, suffixes, and particles ( "Okurigana"), and for the aforementioned ruby text.
