Extremely thin — so thin it is almost see-through. A wafer is a very thin, flat, crisp biscuit (the kind you get with ice cream, or the thin round bread used in a Christian church service), so calling something wafer-thin means 'as thin as one of those'.

Extremely thin極薄 — so thin it is almost see-through薄到幾乎透光。 A wafer「wafer」 is a very thin, flat, crisp biscuit是一種很薄、扁平、酥脆的餅乾 (the kind you get with ice cream, or the thin round bread used in a Christian church service)(就是配冰淇淋吃的那種,或是基督教教會儀式用的那種薄圓麵餅), so calling something wafer-thin所以說某個東西「wafer-thin」 means意思就是 'as thin as one of those'「像那種東西一樣薄」。

You use it for real physical things: wafer-thin slices of ham, a wafer-thin phone, a wafer-thin layer of chocolate. It sounds slightly admiring when the thinness is clever (a wafer-thin laptop) and slightly complaining when you feel cheated (wafer-thin slices of beef in an expensive sandwich).

You use it你會用在 for real physical things真實的實體東西上: wafer-thin slices of ham薄薄的火腿片, a wafer-thin phone薄型手機, a wafer-thin layer of chocolate一層薄薄的巧克力。 It sounds slightly admiring聽起來帶點讚賞 when the thinness is clever當薄得很巧妙的時候 (a wafer-thin laptop)(像是超薄筆電) and slightly complaining帶點抱怨 when you feel cheated當你覺得被坑的時候 (wafer-thin slices of beef in an expensive sandwich)(像是昂貴三明治裡薄薄幾片牛肉)。

It is also very common in a stretched, non-physical way, for something that is only just enough: a wafer-thin majority in an election, a wafer-thin profit margin, a wafer-thin lead in a game. That stretched use is now probably the one you meet most often in news writing.

It is also very common它也常常用 in a stretched, non-physical way在延伸、非實體的意思上, for something that is only just enough指剛好夠、沒有多少空間的東西: a wafer-thin majority in an election選舉裡極微弱的多數, a wafer-thin profit margin極微薄的利潤, a wafer-thin lead in a game遊戲裡極小的領先。 That stretched use這種延伸用法 is now probably the one you meet most often現在大概是你最常遇到的 in news writing在新聞寫作裡。

It is always written with a hyphen before a noun, and it stays hyphenated after 'be' too — 'the walls are wafer-thin'. It is an adjective only; there is no verb and no adverb.

It is always written with a hyphen它一定要加連字號 before a noun放在名詞前面時, and it stays hyphenated after 'be' too放在「be」後面時也一樣要加 — 'the walls are wafer-thin'「the walls are wafer-thin牆薄得跟紙一樣」。 It is an adjective only它只能當形容詞; there is no verb and no adverb沒有動詞形式,也沒有副詞形式。
