同義詞
  • all right

    same meaning, slightly more British and a touch more formal

  • sure

  • yes

    plain agreement; less warm than OK in conversation

反義詞

    informal refusal of a request

文法句型

OK, [clause]

OK + period or comma

用法筆記

Almost always spoken or used in chat messages. Avoid in formal writing — switch to 'Yes, I will' or 'Agreed' there. Tone depends on what comes after: 'OK!' sounds keen; 'Oh, OK…' sounds reluctant; flat 'OK.' sounds neutral.

常見錯誤

In my application letter I wrote OK to the offer.
In my application letter I accepted the offer.
💡'OK' is too informal for letters or essays.

2.感嘆詞A2
釋義

added to the end of a sentence with a rising voice to ask the listener whether they have understood, or whether they agree to what you just said.

例句

I will be back home by ten o'clock tonight, OK?

[plan], OK? — checking the listener accepts

Don't tell your sister about the surprise, OK?

instruction + OK? — softens an order

同義詞
  • right

    very similar; common in British speech as a tag

  • all right

    interchangeable here; slightly longer in speech

文法句型

[clause], OK?

rising intonation on OK

用法筆記

Distinguish from sense 1: this OK has rising intonation and sits at the end of the clause as a tag, while sense 1 OK starts a reply. In writing, the question mark is essential — without it, readers will read it as sense 1.

常見錯誤

You will wait here OK.
You will wait here, OK?
💡the comma plus question mark mark the rising-tone tag.

3. said at the beginning of a sentence to signal that you are about to do the next

3.感嘆詞A2
釋義

said at the beginning of a sentence to signal that you are about to do the next thing, often followed by 'let's' or an order to a group.

例句

OK, let's get started — please open your books to page twelve.

OK, let's [verb] — group action signal

OK, everyone, line up by the door for the field trip.

OK, everyone — calling a group to do something

同義詞
  • right

    common British equivalent for kicking off a group action

  • all right

    slightly slower and more deliberate in speech

  • now then

    more old-fashioned; teachers often use it

文法句型

OK, let's [verb]

OK, [imperative]

用法筆記

Different from sense 1 (a reply): here OK starts a new turn and is not answering anyone — it pivots from one moment to the next. Often followed by 'let's', 'time to', or a direct command.

常見錯誤

OK that we begin the meeting now.
OK, let's begin the meeting now.
💡use a comma after OK and follow with 'let's' or an imperative, not 'that…'.

OK between two steps in an instruction

We will fly to Osaka on Friday, OK, and from there take the train to Kyoto.

OK marking a brief pause in a plan

同義詞
  • right

    same pause-filler use, common in British English teaching

  • so

    more common in academic speech for marking the next step

文法句型

[clause 1], OK, [clause 2]

用法筆記

Sounds natural in speech and teaching, but can clutter writing. Drop it in essays and reports. In transcripts, it often marks where a teacher or speaker is checking the listener is still with them.

常見錯誤

In my essay I wrote, “The reason, OK, is that…
In my essay I wrote, “The reason is that…
💡pause-filler OK belongs in speech, not writing.
