The word "竹篾" is formed by directly combining the character "竹", which means bamboo, with "篾", which means thin strip or splint, specifically referring to bamboo-derived material. Together, they create a compound term that denotes thin strips of bamboo, used in contexts like weaving or crafting, through the semantic contribution of each character where "竹" identifies the source material and "篾" specifies its processed form.
