Citadel
“Citadel”是一个名词，主要有两个含义：
- 城堡、要塞：用来防御的坚固堡垒
- 堡垒：比喻保护或防御的地方
- The citadel overlooked the city. (城堡俯瞰着城市。)
- The ancient citadel was well preserved. (古代城堡保存完好。)
- The citadel provided protection for the people. (城堡为人民提供了保护。)
“Citadel”来自意大利语 “cittadella”，由 “città”（城市）和 “-ella”（小后缀）组成，字面意思是”小城市”。
- 词根：cit-（城市）
- 后缀：-adel（名词后缀）
“Citadel”常用于描述用来防御的坚固堡垒，在历史和文学中经常使用。

可以将 “citadel” 与 “city”（城市）联系起来，两者都与城市、堡垒有关。
When I visited the old citadel, I was amazed by how well it was built - thick walls, strategic location, and multiple layers of defense. It must have been nearly impossible to attack. Standing there, I could imagine what it was like to live in a time when such fortifications were necessary for survival.
当我参观旧城堡时，我对它的建造方式感到惊叹——厚墙、战略位置和多层防御。攻击它一定几乎不可能。站在那里，我可以想象在这样一个防御工事对生存必要的时代生活是什么样子。
