The kanji 師 is a 形声文字 (keisei moji), which means a character that combines a semantic component (meaning component) and a phonetic component (sound component). It is composed of the radical ⺹, which is the "hand" radical, and the phonetic component 帀. The 帀 component originally was a pictograph representing a belt or cloth tied around something, which might be interpreted as a symbol of guidance. The whole character likely suggests someone who guides or instructs others with their hands, showing expertise and skill, hence the meaning of "master" or "teacher".
