無茶
むちゃ · mucha · JLPT N1 · na-adj
absurd
🫖 Etymology: short for 無茶苦茶 mucha-kucha, a chaotic mess; 無 = none, so no sense at all
無 means none or without, and 茶 means tea. The word is a shortened form of 無茶苦茶 (mucha-kucha), a chaotic jumble with no reason or order, so absurd fits.
茶 — grass radical 艹 + 余 (phonetic)
茶 combines the grass radical 艹, indicating a plant, with 余 serving as the phonetic component. It originally derived from the older character 荼, which referred broadly to bitter herbs; a stroke was dropped during the Tang dynasty to distinguish the tea plant specifically. Today it means tea.
