air castle

air castle 的音标是 [ˈeə kɑːlz]，基本翻译是“空中楼阁”，速记技巧是“空气城堡”。

Air Castle这个词源自英语，它的词源可以追溯到古英语中的“aera”和“castellum”两个词。其中，“aera”意为“地方”或“区域”，而“castellum”则意为“城堡”。因此，“air castle”可以理解为“空中城堡”或“虚幻城堡”，表示一种不切实际或空想的想法或计划。

这个词的变化形式主要有复数形式“air castles”和过去式、过去分词形式“air-castle’d”和“air-castle’d”。

相关单词方面，除了“air castle”本身，还可以包括以下单词：castle（城堡）、area（地区）、幻想、空想、白日梦、梦想、虚构、不切实际、空中楼阁等。这些单词都与“air castle”有某种程度的关联，表达了不同程度的不现实或空想含义。

例如，当我们说一个人有“幻想”或“空想”时，我们指的是他们有过于理想或不切实际的想法；而“白日梦”则是指一个人在做某事时，头脑中想象着一些不现实的情景；至于“虚构”和“不切实际”，它们直接与“air castle”的含义相符，表示一种完全不现实的或虚构的想法或计划。总之，这些单词都与“air castle”有着密切的语义关联。
