The kanji 鉄 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is 金 (kin), which is a radical meaning "metal" or "gold." The right side is 失 (shitsu), which provides the phonetic component, suggesting the sound "tetsu." Together, they combine to indicate the meaning "iron" as a type of metal. Historically, the character evolved to its current form to represent this specific metal element.
