Origin

The character combines the flesh radical 月 on the left—which appears in most body-part kanji—with the sound component 彭 on the right. The component 彭 suggests the pronunciation, while the flesh radical tells you this is about the body swelling or expanding. When flesh or muscle expands outward, it becomes thick and puffy, which is the core meaning. So the overall shape points to physical enlargement, particularly of the body or soft tissues.
