Origin

This character combines a hand component on the left, which signals an action you do with your hands, with a sound hint on the right that tells you roughly how to pronounce it. The hand element points toward the physical act of boarding or loading—you use your hands to climb onto or place something into a vehicle. The right component is primarily there to hint at the character's pronunciation rather than add meaning. Together, the hand action plus the sound indicator create a character that means to board, load, or ride.
