Examples:

"[Les] McCann, who would later serve as a drummer and horn player in his high-school marching band, soon developed a love for the great symphonies and for distinctive rhythm and blues vocal stylists such as Bullmoose Jackson, Billy Eckstine and Louis Jordan. But it was the ebullient gospel music he heard at his local Baptist church that touched him the deepest. 'That was the foundation, the basis for all of my knowledge,' says McCann, whose rollicking piano work still bears a strong gospel tinge." — George Varga, The San Diego Union-Tribune, 4 Jan. 2024

Did you know?

Someone who is ebullient is bubbling over with enthusiasm, so it shouldn't be much of a surprise that ebullient comes from the Latin verb ebullire, which means "to bubble out." When ebullient was first used in the late 1500s its meaning hewed closely to its Latin source: ebullient meant "boiling" or "bubbling," and described things like boiling water and boiling oil instead of someone's bubbly personality. Only later did the word's meaning broaden beyond describing the liveliness of a boiling liquid to encompass emotional liveliness and enthusiasm.
