Someone who is exultant is full of that leaping joy and pride — they have just succeeded, and it shows on the face, in the voice, in the way they stand. It is a rather formal, bookish adjective. You might read “exultant fans” or “an exultant smile” in a newspaper. In speech, people more often say overjoyed, thrilled, or delighted. Though actually, exultant still keeps a hint of winning: it is happiness with a score attached, not the quiet happiness of a peaceful afternoon. You can be happy without being exultant; this word is for the burst that follows a result you wanted.

歡欣鼓舞的；得意洋洋的
