Origin

The character 稽 combines wood (the lower part, representing something solid or structural) with a component suggesting the idea of pausing or stopping (the upper part). Together, these elements depict the physical act of leaning or resting against something wooden—like pausing to think while touching a support. This image of stopping and stabilizing oneself gradually came to mean the more abstract idea of thinking or considering, since reflection requires you to pause and hold your thoughts steady.
