The kanji 逓 is a 形声文字 (keisei moji), a phono-semantic compound. The left side, 辶 (しんにょう - shinnnyou), which is a simplified form of ⻌, acts as the semantic component, indicating movement or going. The right side, 弟 (テイ - tei), is the phonetic component, indicating the sound and has the meaning of "younger brother". The original meaning of 逓 was linked to the act of passing things or transferring them, similar to the younger brother following his older sibling. Over time, it evolved to represent sending or transmitting more generally. The component 弟 implies an order or succession within the movement.
