未熟
みじゅく · mijuku · JLPT N1 · na-adj
immature
🌱 未 (not yet) + 熟 (ripe): not yet ripe, like unripe fruit, so still green and inexperienced
Mi-ju-ku: 未 means 'not yet' and 熟 means 'ripe' or 'mature'. Something unripe is green and not ready to eat, which maps to a person who lacks skill or experience yet.
未 — tree 木 with extra short top stroke
未 originally pictured a tree with luxuriant new branches at the top, suggesting tender shoots not yet matured. From this 'not yet ripe' image it came to mean 'not yet' or 'have not.' It is also the 8th Earthly Branch, used in the traditional sexagenary cycle.
熟 — 享 (offering) + 灬 (fire)
Originally written 孰, depicting hands offering food (享) for cooking. The fire radical 灬 was later added to emphasize cooking with heat. The core sense 'cooked' extended naturally to 'ripe,' 'familiar,' and 'skilled through repeated practice.'
