這個拼法底下其實是2個不同的字，意思沒有關係， 只是長得一樣。下面分開列出來。跳到 inside layer, lining bag · passenger ship
liner
nounFor this group you can picture the layer that sits inside something else. A bin has a bag in it. A cake tin has a paper cup in it. A coat has a soft layer buttoned into it. A record case has a folded sheet of paper tucked into it. In every one of those pictures the outside thing is the container, the inside layer is thin and shaped to fit, and it can be pulled out and replaced when it is dirty, worn, or simply finished with. Whatever we call the container, the liner is the layer we put in.
From the word’s history
Wiktionary records this group as line (verb) + -er: the verb line means to put a layer inside something, so a liner is the thing that does that.
Wiktionary 把這一支記成 line（動詞）+ -er。動詞 line 指「在裡面鋪一層」，加上 -er 就成了「鋪在裡面的那個東西」，剛好對得上內襯和唱片內頁兩個用法。

Wiktionary 把這一支另外記成 line（名詞）+ -er，跟「內襯」那一支來源不同。這裡的 line 是航線、路線、一排的意思，不是「鋪一層」。眼線那個意思來源沒有直接說明歸在哪一支，這裡是依畫面歸類的，屬於教學上的整理，不是歷史主張。
