Filled with or showing a lot of happiness and joy, especially after a success or victory.

Exultant → It is formed from "ex-" (meaning out of or from) and "saltare" (meaning to leap or jump). The word describes a state of being that involves leaping out of joy or happiness.
Think of someone jumping 'out of' ('ex-') joy — that's why exultant means feeling or showing great happiness.
