To be jubilant is to show great joy or triumph. Contrasted with the word happy, which conveys delight but not necessarily to a high (or noisy) degree, jubilant shouts its elation from the rooftops. It comes from the Latin verb jūbilāre meaning "to shout, whoop," and fittingly, you're most likely to find it describing the mood or manner of people gathered in celebration, or with something to "whoop" about, as a success or victory.
Usually when we use the word different, we are describing something that is unlike something else. The word disparate conveys that, too, but the distinction is more pronounced. Items, attitudes, or systems that are disparate are so dissimilar or incongruous that they are difficult to compare, and may indeed seem incompatible. Despite this word's prickly disposition, disparate is often found in discussions of efforts to bring things together or find common ground.
Isn't it amazing how easy it is to overuse the word amazing? Prodigious is a more specific descriptor. Like amazing, prodigious conveys a sense of wonder, but it is used to comment on the size, amount, extent, or degree of what is being described. Items described as prodigious are extraordinary by one of these measures, as a musician with prodigious talent, a research grant of a prodigious amount, or a career notable for its prodigious output.
