Kanji
Readings
Jukujikun are when the standard kanji for a word are related to the meaning, but not the sound. The word is pronounced as a whole, not corresponding to sounds of individual kanji. For example, 今朝 ("this morning") is jukujikun, and read neither as *ima'asa, the kun'yomi of the characters, infrequently as konchō, the on'yomi of the characters, and not as any combination thereof. Instead it is read as kesa, a native bisyllabic Japanese word that may be seen as a single morpheme, or as a fusion of kyō (previously kefu), "today", and asa, "morning". Likewise, 今日 ("today") is also jukujikun, usually read with the native reading kyō; its on'yomi, konnichi, does occur in certain words and expressions, especially in the broader sense "nowadays" or "current", such as 今日的 ("present-day"), although in the phrase konnichi wa ("good day"), konnichi is typically spelled wholly with hiragana rather than with the kanji 今日.
