Effervescent

From Latin "effervescere" (to boil up), from "ex-" (out) plus "fervescere" (to begin to boil), from "fervere" (to boil) — the same boiling root behind "fervent" and "fermentation." The word rose bubbles of meaning from literal fizz to figurative exuberance.

  1. adjective · /ef-ur-VES-unt/

    Giving off bubbles; fizzy — and, of a person, bubbly and full of high spirits.

    The lively sparkle of champagne and soda, lending that same image to describe an irrepressibly cheerful personality.

    She poured the effervescent wine, its bubbles racing up the glass.

    Its bubbles are often a gift of fermentation: in champagne and beer, the fizz comes from carbon dioxide that yeast produces, trapped in the bottle under pressure.
