Where it comes from
Early Modern English effervescent — “bubbling, vivacious” · entered English 17th c.
From Latin 'effervescere,' meaning 'to boil over or bubble up,' formed from 'ex-' (out) and 'fervescere' (to begin to boil), from 'fervere' (to boil or glow). The present participle form 'effervescent' entered English in the late 17th century, first in scientific contexts describing gases or liquids, and later extended metaphorically to describe bubbly personalities.
