To open a buckle — the metal fastener on a belt, a shoe strap, a watch band, a schoolbag, or a seatbelt. You unbuckle a thing by pushing or pulling the metal tongue out of its hole so the two ends come apart. It is a small, plain, physical word: you do it with your hands, and you can hear the click.

To open a buckle解開扣環—— the metal fastener on a belt, a shoe strap, a watch band, a schoolbag, or a seatbelt就是皮帶、鞋帶、錶帶、書包或安全帶上那個金屬扣件。You你 unbuckle a thing解開某樣東西 by pushing or pulling the metal tongue out of its hole靠把金屬舌片從孔裡推出或拉出來 so the two ends come apart讓兩端分開。It它 is a small, plain, physical word是個小小的、樸實的、講動作的字： you你 do it with your hands用手做這個動作， and而且 you你 can hear the click可以聽到「喀」一聲。

Note what it takes as its object. You unbuckle the belt, or the shoe, or the seatbelt — the thing that is fastened. In careful English you also unbuckle the buckle itself, but that sounds a little odd to most ears; people name the bigger thing.

Note注意 what it takes as its object它的受詞會是什麼。You你 unbuckle會解開的是 the belt, or the shoe, or the seatbelt皮帶、或鞋子、或安全帶—— the thing that is fastened就是被扣住的那個東西。In careful English在講究一點的英文裡 you你 also unbuckle the buckle itself也會說解開扣環本身， but不過 that sounds a little odd to most ears這對大多數人聽起來有點怪； people大家 name the bigger thing會講那個比較大的東西。

There is one common extension beyond real buckles: on a plane, the announcement is about the seatbelt sign, and people say "you can unbuckle now" with no object at all, just meaning "you may release your seatbelt." Beyond that, this word stays literal. Unlike some un- verbs, it has not grown a figurative life — you do not unbuckle your feelings or unbuckle a problem.

There is one common extension有一個常見的延伸用法 beyond real buckles在真正的扣環之外： on a plane在飛機上， the announcement is about the seatbelt sign廣播講的是安全帶指示燈， and而 people say 'you can unbuckle now' with no object at all人們會說「you can unbuckle now」，完全不接受詞， just meaning 'you may release your seatbelt.' 意思就只是「你可以解開安全帶了」。Beyond that除此之外， this word stays literal這個字都維持字面意思。Unlike some un- verbs不像有些 un- 開頭的動詞， it它 has not grown a figurative life沒有發展出比喻用法—— you你 do not unbuckle your feelings or unbuckle a problem不會說 unbuckle your feelings 或 unbuckle a problem。

If nothing is fastened with an actual buckle, this is the wrong word: clothes with buttons get unbuttoned, a zip gets unzipped, laces get untied.

If nothing is fastened with an actual buckle如果沒有東西是真正用扣環扣住的， this is the wrong word這個字就用錯了： clothes with buttons有釦子的衣服 get unbuttoned要說 unbuttoned， a zip拉鍊 gets unzipped要說 unzipped， laces鞋帶 get untied要說 untied。
