立つ
たつ · tatsu · JLPT N5 · verb-godan
to stand up
🧍 立 = a person standing on the ground line; tatsu: ta-da, up you get
The kanji 立 began as a drawing of a person with legs apart standing on a ground line, so the character itself means standing. Sound hook: tatsu starts like ta-da, the word you say as you pop up onto your feet.
立 — person standing on ground (大 over 一)
Pictograph of a person standing with arms outstretched on the ground line below. The original oracle bone form clearly shows a frontal human figure planted on the earth. The core meaning 'to stand' extended to 'establish, set up, erect.'
