Someone with esprit is full of life, joy, and vigor. Your esprit might make you a lively camp counselor or an enthusiastic teacher.
The quality of being vivacious and alive, smart and witty, can be summed up in the word esprit. Esprit isn't something everyone has, but people who do are positive and fun to be around. It's a French word that's been used in English since the 16th century, literally meaning "spirit," "soul," or "mind," from the Latin root spiritus, "spirit."
