The kanji 勇 is a 形声文字 (keisei moji), a phono-semantic compound character. The character is formed from two parts: the top part is 甬 (yō), originally a pictograph of a person's chest muscles, which represents "strength" and the bottom part 力 (chikara), meaning "power" or "strength". The combination suggests "strength in the chest," implying courage and valor. Over time, the character evolved to its current form.
