The kanji 媒 is a phono-semantic compound (形声文字, けいせいもじ). It combines the phonetic component 每 (bai, meaning "every" or "each" and acting as the sound element) with the semantic component 女 (onna, meaning "woman"). The original meaning may have related to matchmakers or women who facilitated marriages. The 女 (woman) radical gives a clue to its early association, and the 每 (bai) indicates the sound and potentially suggests the frequency or repetition involved in the intermediary process. It developed to include any agent or medium.
