to promote (an idea or cause); to advance; boost
🏃💨 促 = urge + 进 = advance; together: urge forward, promote
促 (cù) means to urge or hurry; 进 (jìn) means to advance or enter. Combined, 促进 literally means to urge-advance — to push something forward, promote, or accelerate progress.
进 — walk radical 辶 + well 井
Originally a semantic-phonetic compound: the walking radical 辶 gives the meaning of movement, while 井 (jǐng, 'well') supplied the sound. The traditional form 進 used 隹 (short-tailed bird) suggesting forward flight; the simplified 进 swapped 隹 for the simpler phonetic 井. The core meaning 'to advance, enter' has stayed stable.
