So good that nothing else comes close. It is a compliment word, used for skill, quality, beauty, success — 'her knowledge of the subject is unmatched', 'a view unmatched anywhere on the island'.

So good好到 that nothing else comes close沒有別的東西比得上。It is a compliment word這是一個稱讚用的字, used for skill, quality, beauty, success用在技巧、品質、美麗、成就上 — 'her knowledge of the subject is unmatched''her knowledge of the subject is unmatched'（她對這個主題的知識無人能及）, 'a view unmatched anywhere on the island''a view unmatched anywhere on the island'（這個景色在島上其他地方都看不到）。

The logic inside it is a small competition: to match something is to equal it, so if nothing has matched it, it stands alone at the top. That makes it stronger than 'very good' and roughly as strong as 'the best', but with a nicer sound, because it praises by saying what others failed to do rather than boasting outright. It belongs to fairly formal or written English — reviews, advertising, speeches at retirements — and would sound grand in casual chat.

The logic inside it它內部的邏輯 is a small competition其實是一場小小的競賽: to match somethingto match something（比得上某樣東西） is to equal it就是跟它相等, so if nothing has matched it所以如果沒有任何東西比得上它, it stands alone at the top它就獨自站在頂端。That makes it stronger than 'very good'這讓它比'very good'更強 and roughly as strong as 'the best'強度大概跟'the best'差不多, but with a nicer sound但聽起來更好聽, because it praises by saying what others failed to do因為它是靠說出別人做不到的事來稱讚 rather than boasting outright而不是直接自誇。It belongs to fairly formal or written English它屬於相當正式或書面的英文 — reviews, advertising, speeches at retirements評論、廣告、退休典禮上的致詞 — and would sound grand in casual chat放進日常閒聊裡會顯得很誇張。

Two other uses exist and are quite different: 'unmatched' can simply mean not paired up, as with socks or gloves that have lost their partner, or data records that did not find a match. Context tells you instantly which one is meant, since the praising sense almost always attaches to a quality, and the pairing sense to countable objects.

Two other uses exist and are quite different還有兩種完全不同的用法: 'unmatched' can simply mean not paired up'unmatched'也可以單純指沒有配成一對, as with socks or gloves that have lost their partner像是少了另一隻的襪子或手套, or data records that did not find a match或是找不到對應項的資料紀錄。Context tells you instantly which one is meant上下文會馬上告訴你是哪一種意思, since the praising sense almost always attaches to a quality因為稱讚的用法幾乎都是搭配某種特質, and the pairing sense to countable objects而配對的用法則是搭配可數的物品。

You will also meet 'unmatchable' and, with the same meaning, 'unrivalled' and 'unequalled'.

You will also meet你也會遇到 'unmatchable''unmatchable' and, with the same meaning以及意思相同的, 'unrivalled' and 'unequalled''unrivalled'和'unequalled'。
