未だ
いまだ · imada · JLPT N1 · adverb
still
⏳ 未 = not yet, as in 未来 (future) = not-yet-come; いまだ = still not yet
未 means not yet, the same root as 未来 (future, the not-yet-come). Used with negatives, いまだ means still: 未だ来ない = still hasn't come.
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.
