The kanji 復 is a phono-semantic compound (形声文字 - keisei moji). The semantic component is 彳 (gyou-nyou - a variant of 行, which signifies "to walk" or "to go") and the phonetic component is 畐 (fuku - it provides the sound). Therefore, the original meaning of 復 is to go back and forth. Later, it expanded to include the meanings of "return," "revive," or "restore". The 畐 part also gives the sound of the character.
