The kanji 摩 generally conveys the idea of rubbing, grinding, or polishing something. It often implies a process of friction or contact that results in a change to the surface of an object or the act of wearing something down. It can also extend to ideas of touching, coming into contact, or even the act of "wearing away" in a metaphorical sense.

The kanji 摩 is a phono-semantic compound (形声文字). The semantic component is 手 (te), meaning "hand," providing the meaning element, as rubbing is done by hand. The phonetic component is 麻 (ma), which suggests the sound. The combination of these components indicates rubbing or grinding something, especially using one's hands. The character has evolved over time, retaining its association with the concept of friction and contact.
