释义
n.
A tall, fast-growing evergreen tree native mainly to Australia, valued for its aromatic oil and timber
桉树,尤加利树
词根拆分
词根派生eu-(好、妥帖)+ calyptus(希腊语 kalyptos = 覆盖)=「盖得好」。这树以花苞命名,而非叶子:每个花苞戴一顶整齐的小帽(盖瓣),把自己盖得严实,开花时帽子才脱落。
词根 eu 还连着 4 个词为什么是这个意思
kalyptos「覆盖」这个词根有个有名的表亲:apocalypse 是 apo-(去掉)+ kalyptos =「揭开覆盖」,即天启、揭示。所以桉树花苞是「盖得好」,而 apocalypse 是把世界的盖子掀开。同一词根,方向相反。
