This sense lives in a set phrase. Without further ado, or without more ado, means ‘now, without waiting, without extra talk or fuss.’ A host says it before they start: ‘Without further ado, here is our guest.’ The word ado by itself is an old noun meaning fuss, busy noise, trouble about something — Much Ado About Nothing is a famous title, and it means a lot of noise about a small thing.

This sense這個意思 lives in a set phrase存在於一個固定片語裡。Without further ado, or without more ado「無須贅言」或「不再囉唆」, means '現在，不等待，不多說廢話'now, without waiting, without extra talk or fuss。A host主持人 says it before they start會在開始前這樣說：'Without further ado, here is our guest.'「廢話不多說，這位就是我們的來賓」。The word ado by itselfado 這個字單獨來看 is an old noun是個古老的名詞 meaning fuss, busy noise, trouble about something意思是無謂的忙亂、吵鬧、麻煩事——Much Ado About Nothing《無事生非》 is a famous title是個有名的劇名，and it而它 means a lot of noise about a small thing意思是為了小事鬧出很大的動靜。

So ‘without ado’ is ‘without that fuss.’ It is a little theatrical and a little old, but people still say it when they want to sound as if they are getting on with it. You would not say ‘I had an ado’ in modern talk, and you would not use ado by itself to mean ‘delay.’

So所以 'without ado'「without ado」 is 'without that fuss.'意思就是「不用那些瞎忙」。It它 is a little theatrical and a little old有點戲劇化又有點老派，but people不過大家 still say it when they want to sound as if they are getting on with it想表現出馬上要開始做事的樣子時還是會這樣說。You你 would not say 'I had an ado' in modern talk在現代口語裡不會說 'I had an ado'，and you而且 would not use ado by itself to mean 'delay.'也不會單獨用 ado 來表示「延遲」。
