Origin

This character pairs the bone radical on the left, which suggests something structural or fundamental, with the character meaning "straight" on the right, which serves as a sound hint for the pronunciation "shoku." The bone component was originally chosen because growth and multiplication are processes that build up the body and bones, making it a fitting visual metaphor for increase. Over time, the combination came to represent the abstract idea of augmentation and growth in general, moving beyond just physical development.
