Loony
“Loony” 可作名词和形容词。作名词时，指精神失常或非常愚蠢的人；作形容词时，形容人疯狂或事物荒谬可笑。源自 “lunatic”（疯子）的俚语变体，带口语、调侃色彩，正式场合应避免使用。
- “That guy shouting at the pigeons in the park is a complete loony.” (在公园里对鸽子大喊的那个人完全是个疯子。)
- “It was a loony idea to try to cross the desert without water.” (不带水穿越沙漠真是个荒谬的主意。)
- “She went loony after losing her job and started talking to the walls.” (失业后她变得疯疯癫癫，开始对着墙说话。)
源自 “lunatic” 的缩写。Lunatic 来自拉丁语 “luna”（月亮），古人认为月相变化会影响人的精神，故有 “moonstruck”（月疯）之说。
- 词根: luna（月亮）→ lunatic（疯子）→ loony（俚语变体）
- 无典型前缀后缀
“Loony” 在英式英语中较常见，常与 “loony bin”（疯人院）连用。因与 “loon”（潜鸟）发音相近，有时会产生联想。使用时需注意，该词可能冒犯精神疾病患者，正式或敏感语境应避免。
- 固定搭配: “loony bin” (疯人院，俚语), “go loony” (变疯)
- 比较级: loonier；最高级: looniest
- 名词: looniness
Loony 来自 lunatic（疯子），记作 “luna”（月亮）的变体。古人认为月亮会让人发疯，故有 “lunatic”。
“The old man had a loony theory that the government was controlling the weather with secret satellites. His neighbors thought he was a bit loony, but they still invited him to barbecues. After all, his stories were entertaining, even if they made no sense.” (那位老人有个荒谬的理论，认为政府在用秘密卫星控制天气。邻居们觉得他有点疯，但还是会邀请他来烧烤。毕竟，他的故事虽然毫无道理，却挺有意思。)
