常見錯誤
What are common mistakes with "Birthday"?Which "Birthday" sentences look correct but are wrong?
×I will go to my friend birthday.
✓I will go to my friend's birthday party.
「birthday」本身是一個日期或概念，通常不會直接「去」一個日期。要表達參加慶生活動時，應使用「birthday party」或「birthday celebration」。
×My birthday is on January.
✓My birthday is in January.
表達生日在「某月」時，介系詞應用「in」。只有當日期包含具體的「日」時（如 January 5th），才用「on」。
×Happy birthday to you! — I'm 20 years old birthday.
✓Happy birthday to you! — I'm 20 years old today. / It's my 20th birthday.
在回應生日祝福或說明年齡時，「birthday」是名詞，不能直接與「years old」並列作形容詞使用。應分開表達年齡和生日。
×I forgot his birthday date.
✓I forgot his birthday. / I forgot the date of his birthday.
「birthday」本身已包含「日期」的概念，因此「birthday date」是冗餘的說法。直接說「birthday」即可，或使用「the date of his birthday」來特別強調日期本身。
×This gift is for your birthday.
✓This gift is for your birthday. (Contextually fine, but often better:) This is a birthday gift for you. / This is for your birthday.
原句文法上沒有錯誤，但在自然口語中，母語者更常使用「This is for your birthday」或「This is a birthday gift/present for you」。使用「for your birthday」作為禮物的修飾語聽起來更自然。
×Congratulations for your birthday!
✓Happy birthday!
在英語文化中，生日祝福通常不說「Congratulations」，除非是針對一個特別的里程碑（如 100 歲生日）。標準的祝福語是「Happy birthday!」。
