The kanji 進 is a phono-semantic compound (形声文字 keisei moji). The left side, 辶 しんにょう, is a simplified form of ⻌ しんにょう, which is a radical indicating movement or going. The right side, 隹 すい, originally depicted a bird. Together, the characters suggest a bird flying forward. Over time, the meaning of "to advance" and "to progress" developed from this imagery.
