拉动
lādòng · HSK 7
Pull
🪢 拉动 = 拉 (pull) + 动 (move): pulling something into motion
拉 means pull and 动 means move or motion, so 拉动 is to pull something so it moves. The lā in 拉 sounds like the start of the English word laggard being dragged along.
拉 — hand radical 扌 + 立 (stand, phonetic)
拉 is a semantic-phonetic compound. The hand radical 扌 indicates an action done with the hand, while 立 (lì, 'stand') supplies the sound, shifted to lā. The original sense is to pull or drag with the hand, which remains its core meaning today.
动 — force 力 + heavy/重 (simplified from 動)
The traditional form 動 combines 重 (heavy) as the phonetic with 力 (force/strength) as the semantic, suggesting the effort needed to move something heavy. The simplified form 动 replaces 重 with 云, keeping 力 to convey action and motion.
