Today’s #kanji is 寝, which is listed under the radical of #うかんむり（宀）. 寝 used to be written as 㝲 and it is a character comprising a semantic and a phonetic element but because both parts are not used in the Japanese language, I cannot show you how it breaks down.
Meaning: to sleep, to lie down
寝室（シンシツ）: a bedroom
寝台（シンダイ）列車（レッシャ）: a sleeper (train)
就寝（シュウシン）する: to go to bed, to turn in, to retire (for the night)
