Etymology: "Upleap" is a plain compound: the prefix "up-" joined to "leap," the familiar verb for springing off the ground. It comes from Middle English "uplepen," which was built the same way, so the word is English-made rather than borrowed from another language. The "up-" in such verbs adds the sense of upward movement, so "upleap" spells out the direction that "leap" alone might leave implied. The word also has relatives in neighboring languages. Dutch "oplopen" and German "auflaufen" share the same up-plus-running-or-leaping construction, though their meanings have drifted: the Dutch verb can mean "to incur" or "run up" (as a debt or bill), and the German can mean "to accumulate" or "run aground." That the same pattern produced both a sense of upward motion in English and accumulation or grounding in German shows how one prefix-and-verb pairing can branch in different directions across related languages.
