illusion vs. delusion
- Illusion 通常指由感官或特定情境造成的錯覺、幻象，它本身是客觀存在的，但被大腦錯誤解讀。例如視覺錯覺或魔術造成的幻象。
- Delusion 則是一種堅定不移的錯誤信念，通常與精神狀態或病理有關，即使有明確的證據反駁也無法動搖。
- 簡單來說，illusion 是「眼睛（或感官）欺騙了你」，而 delusion 是「想法（或信念）欺騙了你」。 EN: The mirage in the desert is a classic optical illusion. 翻譯: 沙漠中的海市蜃樓是經典的視覺幻象。
EN:He suffers from the delusion that he is a famous historical figure.

常見錯誤
What are common mistakes with "Illusion"?Which "Illusion" sentences look correct but are wrong?
×He has an illusion that he is rich.
✓He has the illusion that he is rich.
當指特定、已知的幻覺或錯覺時，通常使用定冠詞 'the' 而非不定冠詞 'an'。
×The magician created an illusion of a disappearing bird.
✓The magician created the illusion of a disappearing bird.
在描述魔術師、藝術家或特定情境「創造出」的某種具體幻覺效果時，通常使用定冠詞 'the'，因為它指涉的是表演中那個特定的、被創造出來的幻象。
×Don't have illusion about getting rich quickly.
✓Don't have any illusions about getting rich quickly.
'illusion' 在此類否定或勸告語句中，常以複數形式 'illusions' 出現，並與 'any' 或 'no' 連用，表示「不抱有任何幻想」。使用單數形式聽起來不自然。
×The oasis was just an illusion in the desert.
✓The oasis was just an illusion / a mirage in the desert.
在沙漠中因光線折射產生的視覺假象，更精確的用詞是 'mirage'。雖然 'illusion' 在廣義上可指任何錯覺，但在這個特定情境下，'mirage' 是更地道、更專業的選擇。兩者皆可，但 'mirage' 更佳。
×It's an illusion to think that money brings happiness.
✓It's an illusion to think that money brings happiness. (可接受) / It is an illusion that money brings happiness. (更常見)
以 'It is an illusion that...' 開頭的句型比 'It's an illusion to think that...' 更為簡潔和常見。前者直接陳述「某事是個幻覺」，後者則略顯冗長。
×Her perfect life is all illusion.
✓Her perfect life is all an illusion.
在 'all' 後接可數名詞單數 'illusion' 時，需要不定冠詞 'an'，構成 'all an illusion' 的慣用說法，意為「完全是個幻覺」。省略冠詞是錯誤的。
