bubbleyoudaoicibaDictYouDict[bubble 词源字典]
bubble: [14] Several Germanic languages have words that sound like, and mean the same as, bubble – Swedish bubla, for instance, and Dutch bobbel – but all are relatively modern, and there is no evidence to link them to a common source. As likely as not, the whole family of bubble words represents ultimately an attempt to lexicalize the sound of bubbling, by blowing through nearly closed lips.
