释义 | acacia (once / 2944 pages) n An acacia is a kind of tree or bush that grows in very warm climates. If you visit Australia, you're likely to see an acacia. Acacias are found in places like South America, Africa, and parts of Asia, though the majority of acacias grow in Australia. Many acacias have tiny leaves and are covered in thorns, although there are varieties that aren't thorny — still, the name itself comes from the Greek word akakia, "thorny Egyptian tree," probably rooted in ake, or "thorn."
