The kanji 曹 is a phono-semantic compound (形声文字, keisei moji). The character is composed of the radical 曰 (meaning "to say" or "speak") and 且 (a phonetic component). The original meaning of 曹 was likely related to the "officials" who were responsible for speaking and making decisions within a court or administrative setting. Over time, the character evolved to encompass the general concept of a group or collection, particularly in the context of official bodies and administration.
