Etymology

Origin of ebullient

First recorded in 1590–1600; from Latin ēbullient- (stem of ēbulliēns “boiling up,” present participle of ēbullīre ), equivalent to ē- + bulli- (derivative of bulla “a bubble”) + -ent-; see origin at e- 1, boil 1 ( def. ), -ent

Explanation

More than chipper, more than happy, more than delighted is ebullient — meaning bubbling over with joy and delight. There are two senses of the word of ebullient. One describes an immediate, and ultimately short-lived, reaction to a particular event — for example if you've just won the lottery, you are ebullient. The other describes someone who is perpetually upbeat and cheerful, for example, as in "an ebullient personality." Watch out for ebullient personalities: they can often be "over the top" as well.
