So it is a word for pushing back, quietly, against a doubt that someone might have — or that the listener might be about to raise. Because of this, it often shows up when the speaker is being fair to someone they otherwise disagree with: 'He has undoubted ability, but he is difficult to work with.' The 'but' is coming, and 'undoubted' pays the compliment fully before it arrives.

So it is a word所以這是一個詞 for pushing back, quietly用來悄悄反駁 against a doubt that someone might have某人可能有的懷疑 or that the listener might be about to raise或聽者可能正要提出的懷疑 Because of this正因如此, it often shows up它常常出現 when the speaker is being fair當說話者想公平對待 to someone they otherwise disagree with一個他們其實不同意的人: 'He has undoubted ability, but he is difficult to work with.'「他有無庸置疑的能力，但他很難共事。」 The 'but' is coming「但是」就要出現了, and而 'undoubted' pays the compliment fully「undoubted」把稱讚給得夠足 before it arrives在但是來之前

It feels formal — you meet it in writing, in news, in speeches, in reviews. Two people talking over lunch would more likely say 'she's definitely talented'.

Though actually, the logic of the word is a little dishonest, and it is worth telling students this. Nobody counts up who doubts. When a writer says 'the undoubted truth', what they mean is 'I am sure, and I would like you to be sure too.' Sometimes it is used exactly where doubt DOES exist, and the word is doing the work of shutting the doubt down.

Though actually不過老實說, the logic of the word這個詞的邏輯 is a little dishonest其實有點不誠實, and而且 it is worth telling students this這點值得告訴學生 Nobody counts up who doubts沒有人真的去算有誰在懷疑 When a writer says當作者說 'the undoubted truth'「無庸置疑的真相」, what they mean is他們的意思是 'I am sure, and I would like you to be sure too.'「我很確定，也希望你也確定」 Sometimes它有時候 it is used exactly where doubt DOES exist正是用在真的有懷疑存在的地方, and而 the word is doing the work of shutting the doubt down這個詞的作用就是把懷疑壓下去

So read it as a strong claim, not as a measurement. Also note: it does not sit comfortably after 'be'. 'His talent is undoubted' is possible and you will meet it, but it sounds formal and slightly old; 'It is undoubted that...' sounds stiff to most ears now.

So所以 read it as要把它看作 a strong claim一個強烈的主張, not as a measurement而不是一種衡量 Also note另外要注意: it does not sit comfortably after 'be'它接在 be 動詞後面不太自然 'His talent is undoubted'「他的才華無庸置疑」 is possible and you will meet it是有可能出現、你會看到, but但是 it sounds formal and slightly old聽起來正式又有點老派; 'It is undoubted that...'「無庸置疑地……」 sounds stiff to most ears now現在大多數人聽起來會覺得很生硬
