Why “ebullience” is a great word
EBULLIENCE — [Noun] The state of being energetically and effervescently enthusiastic, as if bubbling over with high spirits. From Latin ēbullientem, present participle of ēbullīre ("to boil over"), from ē- ("out") + bullīre ("to bubble, boil"), from bulla ("bubble") + English suffix -ence (denoting a state or condition). First attested in English c. 1749. Unlike "exuberance," which suggests an abundant, perhaps unrestrained vigor, or "cheerfulness," which denotes a placid optimism, ebullience is the very act of enthusiasm boiling up and spilling over. It is the percussive chatter of a sunlit creek over stones, the sudden, fizzy hiss when a bottle is uncorked, and the bright, uncontained laughter that escapes a room before the door is opened—a testament to the forces within that press always toward expression.
Etymology
Borrowed from Latin ēbullientem + English -ence (suffix meaning ‘having the state or condition of’). Ēbullientem is the accusative feminine or masculine singular of ēbulliēns (“boiling”), the present participle of ēbulliō (“to boil”) (from ē- (prefix meaning ‘out, away’) + bulliō (“to bubble; to boil”) (from bulla (“bubble; bubble-shaped object”), ultimately from Proto-Indo-European *bʰew- (“to blow; to inflate”))) + -ēns.
