The kanji 同 is a pictophonetic character. It is composed of the radical 冂 (kei, meaning "enclosure") and 口 (kuchi, meaning "mouth"). Originally, 冂 was a stylized version of a shared space or enclosed area, such as a hall, and the 口 was a way of representing the people in the hall. The combined meaning implies "the same hall," "the same people," or "together". Over time, it developed to signify "same" or "alike" because people inside shared the same space.
