The kanji 恐恐 is a 形声文字 (keisei moji), a phono-semantic compound. The character is composed of the radical 心 (kokoro), meaning "heart" or "mind," and the phonetic component 共 (kyō), which provides the sound and contributes to the meaning. The combination of the "heart" radical and the sound/meaning element 共 suggests that the emotion of fear arises from the heart or mind, and is a shared experience. Historically, the character evolved from pictographic representations of someone or something causing fear. The phonetic component, 共, initially a picture of many hands, gradually merged with the "heart" element over time, forming the character as we know it today.
