Origin

This character combines a hand radical on the left, which shows this is about hand actions, with the component 軍 on the right that serves as a sound hint for pronunciation. The 軍 part doesn't contribute to the meaning—it simply indicates roughly how the character should be pronounced. Together, the hand radical paired with this sound hint creates a character meaning to brandish, wave, or swing, capturing the physical motion of moving something energetically with your hand or arm.
