Why this word is great

EBULLIENT — [Adjective] Overflowing with fervent enthusiasm or high spirits, or describing a liquid in a state of agitated bubbling. From the Latin ēbullientem, present participle of ēbullīre ("to boil over"), from ē- ("out") + bullīre ("to bubble, boil"). Unlike "vivacious," which suggests a sociable, animated charm, or "exuberant," which connotes abundant, sometimes lavish energy, "ebullient" captures a pressurized joy that must erupt. It is the champagne froth escaping the bottle neck, the percussive rattle of a lid on a boiling pot, and the first frantic chorus of birds at dawn—a celebration so forceful it seems a brief triumph against the gravity of the everyday.
