Etymology

正 is traditionally explained as 一 (one) over 止 (stop), suggesting a single straight line that stops deviation, hence correctness. The exact historical development is uncertain, but the component explanation is widely used.

Meaning mnemonic

The top line 一 acts as a straight edge, and the bottom 止 stops any crookedness. Together they make everything correct and just.

Reading mnemonic

For セイ, imagine a judge saying 'say' the correct verdict: say -> セイ, and the gavel stops all wrong arguments.
