The kanji 師 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is a part meaning "cloth" or "towel." The right side is a phonetic component that suggests "to be in charge," "to be a leader." The combination of these parts originally depicted a person in charge of a group or field and someone who is excellent in that field. Over time, it evolved to represent a master or teacher.
