Word of the Week

Word of the week is an original meme from Into the Worm's Hole for Mondays. The purpose of this meme is to post an interesting word (mostly in the English language but other languages as well) Any word that sounds nice works(by "sounds nice" I mean if it has a pretty pronunciation or a pretty definition)

                                       Adjective: bubbling, sparkling, lively
                    From the Latin word: effervēscō effervēscere
