start
🔑 启 = open + 动 = move; opening into motion means to start
启 means open or initiate (door radical 户 over 口 mouth, suggesting opening up). 动 means move or action. Together: open + move = start something up, like booting a system or launching an engine.
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.
