jukujikun; special kanji compound reading
A reading assigned to a kanji compound where the characters relate to the meaning but not the pronunciation; e.g. 昨日 (きのう), 大人 (おとな). Used in Japanese linguistics.
Jukujikun is a reading where a native Japanese word is matched to the meaning of the kanji compound.
Reading 明日 as あした is also an example of jukujikun.
