In the Japanese writing system, these are the hiragana characters that follow the kanji for a verb or adjective that add the inflection, such as the "masu" in "ikimasu" (go), the "nai" in "tabenai" (do not eat) and the "manai" in "nomanai" (cannot drink).

Japanese text can often be distinguished from Chinese text by the presence of okurigana and other phonetic characters.
