Used when something is so clearly true or so clearly good that no reasonable person could argue about it. You use it to shut a door: there is nothing here to discuss.

It attaches most often to qualities and facts that are being praised or defended — his unquestionable talent, her unquestionable honesty, the unquestionable success of the plan, unquestionable proof. Notice that it is usually a strong compliment or a strong claim, not a neutral description. It is fairly formal; in daily speech people say 'there's no doubt about it' or 'nobody can argue with that'.

There is a useful pairing to learn here. 'Questionable' means doubtful, suspicious, probably not good — questionable behaviour, a questionable decision. 'Unquestionable' is its opposite: beyond doubt. Both words are really about whether people can raise questions, but they landed in opposite places, and 'questionable' picked up a disapproving flavour along the way.

There is a useful pairing to learn here這裡有一組值得學的對照詞 'Questionable' means 'Questionable'的意思是 doubtful, suspicious, probably not good可疑令人懷疑大概不太好 questionable behaviour可疑的行為 a questionable decision一個令人存疑的決定 'Unquestionable' is its opposite 'Unquestionable'是它的反義詞 beyond doubt意思是無庸置疑 Both words are really about兩個詞其實講的都是 whether people can raise questions人們能不能提出質疑這件事 but they landed in opposite places但它們落在完全相反的意涵裡 and 'questionable' picked up a disapproving flavour along the way而'questionable'在過程中沾染上了一種不贊同的意味

One honest thing to add: 'unquestionable' says nobody CAN reasonably question it, but people often use it about things that are in fact arguable, simply to sound certain. Politicians and advertisements are fond of it. So when you meet it in the wild, it is worth asking yourself quietly whether the thing is really beyond question, or whether the writer just wants you to stop asking.

One honest thing to add有一件老實話要補充 'unquestionable' says 'unquestionable'說的是 nobody CAN reasonably question it沒有人能合理地質疑它 but people often use it但人們常常用這個詞 about things that are in fact arguable來講其實還有得爭論的事情 simply to sound certain只是為了聽起來很篤定 Politicians and advertisements are fond of it政治人物和廣告很愛用這個詞 So當 when you meet it in the wild你在真實情境裡遇到這個詞時 it is worth asking yourself quietly值得悄悄問問自己 whether the thing is really beyond question這件事是不是真的無庸置疑 or whether the writer just wants you to stop asking還是作者只是想要你別再問下去
