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.

Something that is typical is characteristic or distinctive of a certain type or specimen. Something that is quintessential is not only characteristic or distinctive of a type, but goes a step further to capture the pure and essential essence of it—or to embody it perfectly. Quintessential is used to talk about people or things that are exactly as one might imagine or hope for them to be, based on widely circulated and understood ideas or ideals.

To safeguard something is to guard, protect, or secure it. Often this term suggests taking forceful measures to ensure something does or does not happen. As a result, the term conveys a degree of assurance that the safety of something is guaranteed. Safeguard is more likely to be used of ideas or concepts—immaterial things—than it is of property or physical objects. For instance, you’re more likely to hear of a leader or governing body taking measures to safeguard the rights of a specific group than to safeguard a wetland, the latter being better suited for use with the verb protect.
