<注釋>The origins oframbunctious are not clearly established, a situation that may be better understood after looking at the evidence.The development that is generally accepted is from the wordrobustious, derived fromrobust and first recorded in a work written before 548, torumbustious, first recorded in 778, to rambunctious, first recorded in 830, all three words having more or less the same meaning.But how didrobustious lead to rumbustious ô It has been suggested that the wordrumble played a part in this, although the wordrumbustion, meaning .the alcoholic beverage rum,. might also have been involved. The first form in whichrambunctious is recorded is rumbunctious, showing howrumbustious was involved in the alteration of robustious to rambunctious, but how the sound indicated bys became that indicated by nc or why the first u became a is a mystery.
Rambunctious 的詞源并沒有十分清楚地確定， 看一下證據(jù)就能更好地理解這一點。通常認為它的發(fā)展過程是源于robustious 這個詞， 它來自robust 并最早記載于548年以前的一篇作品中， 至于rumbustious 則首次見載于778年， rumbunctious 的最早的文字記載是在830年， 這三個詞的意思大致相同。但是robustious 怎樣演變到 rumbustious 的呢ô 有人認為，rumble 這個詞起了一定的作用， 盡管rumbustion 意為.含酒精飲料甜酒，.但可能也參與了其演變。 Rambunctious 有記載的最早形式是 rumbunctious ， 這表明了rumbustious 這個詞如何參與了從 robustious 到 rambunctious 的演變， 但s 所代表的聲音是如何變成 nc 所代表的聲音的或為什么第一個 u 變成了 a 仍然還是謎
