One way to hold this word: something wide, thin and flat, spread out. That is sheet. The ending -ing can pull in two directions, and this word goes both ways: it can name the flat stuff itself, sold in rolls and cut to length, or it can name the act of something becoming flat layers. So one spelling covers the plastic over a roof, the cloth for a bed, the boards against a bank of earth, the factory step that rolls material out flat, and the rock that splits into curved layers by itself.
From the word’s history
From sheet plus -ing. The base word supplies the flat, spread-out picture; the ending supplies either the material taken as a mass, or the action of forming into sheets.
由 sheet 加上 -ing 構成。sheet 提供「平平一大片」的畫面，-ing 決定往哪邊走：一邊變成「那種料」，一邊變成「變成片的過程」。這個字之所以看起來意思很雜，其實就是這兩條路各自走遠而已。
