The quality or state of bubbling or fizzing, either physically in liquids or metaphorically in behavior and emotions.
From Latin effervescere (to boil up), combining ex- (out) and fervescere (to grow hot, boil). The suffix -ency transforms the verb into a noun describing the continuous state or quality. English borrowed this in the 17th century.
This word captures both the literal science of carbonated drinks releasing CO₂ bubbles AND the figurative sense of someone's bubbly personality—it's one of those rare English words that bridges chemistry and personality perfectly!
