驱动
qūdòng · HSK 7
to drive; to propel
🐎 驱 drive + 动 move = drive something into motion; spur it on
驱 carries the horse radical 马 — its old sense is driving horses forward. Pair it with 动 (move) and you get the push that sets things going: to prompt, urge, or drive.
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.
