Origin

This character combines the radical for flesh or body parts (the left component, which looks like the character for moon) with a sound hint on the right that suggests the pronunciation. Since veins and pulses are physical structures running through the body, the flesh radical makes sense as a classifier. The right component doesn't contribute to the meaning but tells you roughly how to pronounce the character. Over time, the meanings expanded from the concrete idea of veins to include pulse as the rhythmic flow in veins, and then to the figurative sense of hope as a vital thread running through something.
