1.感嘆詞A1
釋義

噢；哦

表示驚訝、欣喜或失望的反應

a short sound a speaker makes the moment they hear, see, or learn something — used to signal surprise, mild shock, sudden pleasure, or quiet disappointment, depending on the tone of voice.

例句

Oh, I didn't know Marcus was your brother!

噢，我不知道 Marcus 是你哥哥！

Oh, + clause expressing surprise at new information

Oh, what a beautiful sunset over Tamsui Bay tonight.

噢，今晚淡水灣的夕陽好美。

Oh + 'what a' + noun for sudden admiration

同義詞
  • ah

    softer, more reflective; often signals understanding rather than surprise

  • wow

    stronger amazement, mostly positive

  • ooh

    drawn-out delight or appreciation, especially of something attractive

文法句型

Oh, + clause

Oh! (standalone)

用法筆記

Tone of voice carries the emotion — written 'oh' is ambiguous between pleasure and disappointment, so context or a following comment usually clarifies. Distinguish from sense 2 (sudden idea) and sense 3 (paired with another exclamation like 'oh no').

常見錯誤

❌Oh that you came!' (no clear emotion or comment).
✅Oh, I'm so glad you came!
💡'oh' should lead into a clause that names the reaction.
❌I said oh when I heard the news.' (used as a verb-like object).
✅I said "Oh!" when I heard the news.
💡quote 'oh' in writing or use a reporting verb like 'gasped'.

2.感嘆詞A1
釋義

對了；啊

突然想起一件事的開頭語

a small filler sound that flags an idea or piece of information popping into the speaker's head mid-conversation, usually so they can add it before they forget.

例句

Oh, before I forget, your dentist called this morning.

對了，趁我還沒忘記，你的牙醫今天早上有打電話來。

Oh + 'before I forget' to insert remembered info

Oh, and please pick up some milk on your way home.

對了，回家路上順便買一下牛奶。

Oh, and + added afterthought

同義詞
  • ah

    more thoughtful, suggests slow recall

  • hey

    more attention-grabbing, can sound abrupt

文法句型

Oh, + remembered statement

Oh, and + added thought

用法筆記

Frequently followed by 'and', 'by the way', or 'I just remembered'. Distinguish from sense 1: this use does not react to what the other person just said but to a thought rising in the speaker's own mind.

常見錯誤

❌I oh remembered to call mom.' (used inside the sentence).
✅Oh, I remembered to call mom.
💡'oh' opens the utterance, set off by a comma.

3. the lead-in word in fixed pairings such as 'oh no', 'oh dear', 'oh God', or 'oh

3.感嘆詞A1
釋義

唉；糟糕

與 no、dear 等搭配表達不滿或難過

the lead-in word in fixed pairings such as 'oh no', 'oh dear', 'oh God', or 'oh come on' — together they release feelings like frustration, sadness, sympathy, or annoyance about a bad piece of news.

例句

Oh no, the milk has gone bad already.

糟糕，牛奶已經壞掉了。

Oh no for small everyday setbacks

Oh dear, poor Mrs. Tanaka has broken her wrist again.

唉，可憐的田中太太手腕又斷了。

Oh dear for sympathetic concern

同義詞
  • alas

    literary, formal, marks regret

  • ugh

    stronger disgust, less sympathetic

  • yikes

    informal, marks alarm with a touch of humour

反義詞
  • hooray

    celebratory opposite — used for good news rather than bad

文法句型

Oh + no/dear/God/come on

用法筆記

Almost always sits in a fixed two-word pair. 'Oh God' and 'oh hell' may offend religious listeners; 'oh dear' and 'oh no' are safe in any company. Distinguish from sense 1, which can stand alone without a partner word.

常見錯誤

❌Oh, no the bus is late.' (comma between the pair).
✅Oh no, the bus is late.
💡keep 'oh' and 'no' together as a unit, then comma.
❌Oh dear me happy birthday!' (mixing with positive news).
✅Oh, happy birthday!
💡'oh dear' carries concern, not celebration.
