The process of bubbles forming and rising in a liquid, often seen in fizzy drinks when gas escapes.
The effervescence of the soda made it refreshing and enjoyable to drink.
Effervescence is formed from "ex-" (meaning out) and "fervere" (meaning to boil). The word describes the process of bubbling or fizzing, as if something is boiling over with energy or excitement.
Think of something 'boiling out' ('ex-') — that's why effervescence means bubbling or fizzing.
