Today’s #kanji is #未, which is apparently a pictogram of a tree with many branches. Then, do you know what 未 means?

Meaning: the eighth of the twelve signs of the Chinese zodiac (time: 2pm, direction: SSW, animal: sheep/goat), with ない, not yet
Reading: ミ、いま（だ）*、ひつじ*、ま（だ）*

未遂（ミスイ）の: ([noun] + の is used like an adjective) attempted
自殺（ジサツ）未遂（ミスイ）: (an) attempted suicide
未成年（ミセイネン）: [noun] minor, minority (under age)
未知数（ミチスウ）: an unknown quantity, an unknown
未定（ミテイ）の: ([noun] + の is used like an adjective) undecided, unfixed, uncertain
未満（ミマン）: [noun] less than
1000円未満: less than 1000 yen = 999 yen or less
For 1000 yen or less, you say 1000円以下イカ
未明（ミメイ）: [noun] the hour before dawn
未来（ミライ）: [noun] future, time to come

未（いま）だかつてない試（こころ）み: something never tried before, a feat never previously attempted
未年（ひつじどし）: the Year of the Sheep
凶器（きょうき）は未（ま）だ見（み）つかっていない:
The lethal weapon has not been found yet.

Do not confuse 未 with 末. The length of a line matters in kanji.
