Think of a cut cliff again, but now you are describing it: this rock is stratified. It has bands, the bands are in order, and you can see the lines between them. Every use of the adjective can be thought of as pointing at something and saying it is built in stacked bands — rock, a society, or a set of data someone has cut into levels.
可以想成你指著一面被切開的岩壁說：這塊石頭是一層一層的。層有順序，層跟層之間有線。這個形容詞的各種用法，就像都在做同一件事——指著某樣東西說「它是分層疊起來的」。石頭是這樣，社會是這樣，被切成幾組的資料也是這樣。
