What does effervesce mean?
To effervesce is to bubble and fizz — most literally, to give off bubbles of gas, as champagne, soda water, or a dissolving antacid tablet does. The verb derives from Latin roots meaning 'to boil up,' and it carries that image of energetic rising motion into its figurative use: a person who effervesces is lively, enthusiastic, and irrepressibly cheerful. In this extended sense it typically appears in the construction 'effervesce with excitement' or 'effervesce with joy,' lending prose a vivid, slightly elevated tone. The word belongs to a small elegant family including the noun 'effervescence' and the adjective 'effervescent.' While the physical sense is everyday and scientific, the emotional sense is favored by writers who want to convey buoyancy more memorably than words like 'bubbly' or 'cheerful' allow. Effervesce is standard in both British and American English.

"Drop the tablet into the water and watch it effervesce."

That satisfying fizz when you drop a tablet into water? English borrowed a whole Latin word just for it — and then let it describe bubbly personalities too.

Etymology of effervesce
Effervesce comes from Latin effervescere, formed from ex- ('out of') plus fervescere ('to begin to boil'), itself from fervere ('to boil'). The word entered English in the early 18th century, first describing liquids that foam or bubble, before extending metaphorically to lively human temperament. It shares the Latin root fervere with related English words such as ferment, fervent, and fervor.
