Synonyms: Happy

Beatus means "blessed" in Latin, so if you have a beatific look on your face that means you're experiencing profound joy.

Blithe shares a root with bliss and bless, and it originally meant "cheerful" and "joyous," as in the famous opening line from Shelley's 1820 poem To A Skylark: "Hail to thee, blithe spirit!" Blithe has also come to mean a quality of being cheerfully unconcerned with something important.

Buoyant things — like buoys — float, bobbing on the water's surface. So if you're in a buoyant mood, you've got a bounce in your step and nothing can bring you down. The word originated in Latin, where boia means "halter," as in the thing you use to tie up a horse, because buoys are anchored in place.

Ecstasy is a pleasure or joy so strong that it takes you outside yourself. This makes sense, since in Greek ekstasis literally means "to put out of place." It was originally used to describe insane people — out of their minds — but also people in religious trances. So if you're ecstatic, you're so happy you're jumping out of your skin.

Euphoria is a Greek word that means "well-bearing" or "healthy," specifically in the sense that you were sick but now feel better. In English, it refers to a powerful feeling of well-being and joy.

Exhilarated shares a root — the latin verb hilarare — with hilarious. To be exhilarated is to be thrilled and elated.

Glee is similar to delight: a happiness that lights up your face with a bright smile.

Jocular and joke share the Latin root ioculus, which means, not surprisingly, "joke."

Iovius is Latin for "of Jupiter," referring to the Roman god of the sky, from which we get his nickname Jove. People born under this sign were believed to be merry and good-humored, so jovial describes those qualities.

Mirth comes from the Old English myrgð, meaning "pleasure" or "bliss." Mirth is the kind of happiness that accompanies laughter, and possibly also involving food, drink, and music — the fun you have with your friends or at parties.

Vivere means "to live" in Latin, so someone vivacious is lively, full of life, the life of the party: somebody who is fun to be around and whose joy is contagious.
