Capable of bubbling, fizzing, or showing lively excitement; able to effervesce.
From Latin effervescere + the English suffix -ible (capable of, able to). This formation follows the standard pattern of creating adjectives from verbs using Latin-derived suffixes.
This word is rarely used today, but it's a reminder that English speakers once actively created new words from scientific verbs—you could theoretically say 'this compound is effervescible' instead of 'can effervesce!'
