The word "雕刻" is formed by combining the characters "雕" and "刻", both of which individually mean to carve or engrave. "雕" specifically conveys carving in detail, often in three-dimensional forms like sculpture, while "刻" emphasizes cutting or incising into a surface, such as in etching. Together, they redundantly reinforce the concept of carving or engraving, resulting in a compound word that denotes the act or art of detailed carving.
