Jubilantly is the how-word that belongs with jubilant. Someone does something in an extremely happy, pleased way because of a success — they wave, shout, hug, or walk out of a room looking as if they could fly. The feeling is the same as jubilant; this form tells you about the action, not the person as a description. “The team was jubilant” paints the team. “The team cheered jubilantly” paints the cheering. It is a bit formal, like the adjective. In easy talk people say “happily” or “they went wild.” Use jubilantly when you want that shouting-for-joy colour. It is simply jubilant plus -ly.
