Origin

This character combines the component for movement or action (動) with a fire-related sound hint at the bottom (灬) that suggests its pronunciation. The top part evokes the idea of dynamic effort and accomplishment, while the bottom component provides a phonetic clue to how the character should be read. Together, the character came to mean meritorious deeds or achievements, as merit typically comes from sustained effort and action. The shape essentially layers a concept of active accomplishment with a pronunciation guide to create a character for describing outstanding service or worthy deeds.
