Start with a cut piece of marble: a pale, cool stone with darker lines wandering through it, never straight, never repeating. The word can point at either half of that picture. Point at the stone and it means the thing is made of marble. Point at the lines and it means the thing only looks that way — paper, glass, a piece of beef. The ending -ed can be read as carrying the look of, which is what lets one word cover both.
The dictionary gives the whole word as marble plus -ed. Read the ending as carrying or bearing, and both uses follow directly: a thing carrying marble as its material, or a thing carrying marble's pattern.
字典把這個字直接記成 marble 加 -ed。把字尾讀成「帶著、具有」，兩個用法就順下來了：帶著大理石這個材質，或是帶著大理石那種紋路。兩邊其實是同一個組合，只是眼睛看向畫面裡的不同地方。

From the picture
花紋：長得像大理石
把眼睛從石頭移到石頭上的線條，剩下的就只是那個花樣：彎曲、不規則、兩種顏色交纏。這個花樣一旦離開石頭，就可以落在紙、玻璃、油漆，甚至一塊牛肉的內部——牛肉裡的白色油花，看起來正是這種紋路。
