Origin

This character combines the hand radical on the left with a phonetic component on the right that suggests the sound "satsu." The hand element indicates an action or something done by hand, while the right side provides the pronunciation hint. The overall shape suggests the idea of pressing or pushing with the hand—the kind of urgent, forceful action that happens when something becomes imminent or draws dangerously close. Over time, this physical sense of pressing inward came to mean that something is approaching or becoming urgent.
