A superabundance of something is a very large amount of it — more than you need, more than is normal, almost too much. It is stronger than 'plenty' and stronger than 'abundance' on its own. If a farm has an abundance of fruit, there is a lot; if it has a superabundance, the trees are heavy, the boxes are full, and some of the fruit will be wasted. The word is formal and a little literary. You will meet it in writing — books, essays, news articles, reports — much more often than in everyday talk, where people just say 'far too much', 'loads of', or 'more than enough'. It is used for physical things you can count or measure (food, water, oil, goods) and just as often for things you cannot (energy, caution, enthusiasm, information, talent). The usual pattern is 'a superabundance of' plus a noun. The feeling is not always positive: sometimes it praises richness, and sometimes it gently complains that there is so much of something that it loses its value. That double feeling is worth noticing — an author who about 'a superabundance of choice' is usually saying that too much choice makes people unhappy.
過剩、極為充裕（多到用不完、甚至有點多過頭）
組成super- (在…之上、超過) + abundance (充裕、大量). Latin super means 'above, over', so the word means an amount that goes above being abundant. Abundance itself comes from Latin abundare, 'to overflow' — a wave washing over the edge.
