Etymology: Bubbling is the present participle of "bubble," and the verb's roots are onomatopoeic. The sound and shape of rising gas breaking through liquid seem to have produced a word that echoes it, and related forms appear across Germanic languages: Middle Dutch "bobbe," Swedish "bubbla," and Danish "boble" all mean the same thing. English may also have been shaped by "burble," which suggests the bubbling of water and voices alike. The most striking shift came in 1720. When the South Sea Company collapsed in a speculative crash, people began using "bubble" for an inflated financial scheme that swells with hype and then pops. The image was an inflated soap bubble bursting, and the economic sense stuck. Writers later extended the metaphor to bubbly, lively talk and high spirits, which is how the word came to describe enthusiasm.
