1.形容詞C2
釋義

describing the duties, time, or work that someone carries out as part of a job that comes with formal responsibility, such as a government or company role.

例句

The mayor's official duties include opening hospitals and meeting visiting leaders.

attributive: official + duties / role / capacity

Senator Park spent her official hours reading new bills and replying to voters.

同義詞
  • professional

    broader: covers any paid expert work, not specifically office-holding

  • work-related

    neutral, no implication of public authority

反義詞
  • personal

    private life rather than job-related

  • private

    outside one's role or position

文法句型

official + noun (duties, capacity, role)

用法筆記

Almost always attributive (before a noun). Distinguish from sense 2: this sense describes the JOB-HOLDER's own activity, while sense 2 describes things sanctioned BY an authority.

常見錯誤

The duty was very official.
It was an official duty.
💡this sense is attributive; predicative use sounds wrong.

2. approved, set up, or carried out by people with the power to make rules — for ex

2.形容詞B2
釋義

approved, set up, or carried out by people with the power to make rules — for example a government, a school, or the leaders of a company — so it counts as the proper version.

例句

The official price of the train ticket from Taipei to Kaohsiung is 1,490 dollars.

attributive: official + concrete noun (price, list, ban)

Lin Yu-ting carried the official flag of Taiwan into the Olympic stadium.

同義詞
  • authorized

    stresses being given permission, slightly more legal in tone

  • formal

    stresses ceremony or set procedure rather than authority

  • approved

    softer; means a decision-maker has agreed, but not necessarily public

反義詞
  • unofficial

    lacking the approval of an authority

  • informal

    outside set procedures, often friendly

文法句型

official + noun

be + official

用法筆記

Subject or modified noun is usually a thing or event that an authority can grant status to (price, language, ceremony, ban, uniform). Distinguish from sense 1: here the focus is on AUTHORIZATION, not on whose job it is.

常見錯誤

I made an official with the bank yesterday.
I made an official complaint to the bank yesterday.
💡'official' is an adjective here; it must modify a noun like complaint, request, or visit.

3. of news, results, or facts: confirmed in public by someone in charge, so people

3.形容詞C2
釋義

of news, results, or facts: confirmed in public by someone in charge, so people can now treat the information as definite rather than rumour.

例句

It's official: Maria and Daniel are getting married next spring in Lisbon.

fixed opener: It's official (+ that-clause / colon)

The election results became official at midnight, after every district had counted its votes.

同義詞
  • confirmed

    neutral; doesn't imply a public authority

  • public

    stresses that the news is now widely known

反義詞
  • unofficial

    not yet publicly confirmed; rumoured

  • rumoured

    talked about but not yet announced as fact

文法句型

it's official (that-clause)

make + something + official

用法筆記

Frequently predicative, especially in the colloquial opener 'It's official, ...'. Subject is typically a piece of news, a result, or a status change. Differs from sense 2 (AUTHORIZED): here the news already exists; the authority simply CONFIRMS it publicly.

常見錯誤

It's official Maria and Daniel are getting married.
It's official: Maria and Daniel are getting married.
💡use a colon, dash, or 'that' after this opener.

4. of a language, name, or currency: formally adopted by a national or regional gov

4.形容詞B2
釋義

of a language, name, or currency: formally adopted by a national or regional government as the one used for laws, schools, and public documents.

例句

Mandarin is one of the official languages of Singapore, alongside English, Malay, and Tamil.

official + language(s) — list pattern with 'alongside'

The official currency of Japan is the yen, and shops rarely accept other money.

同義詞
  • national

    broader; can include culture and identity, not just legal status

  • state

    as in 'state language', stresses government adoption

反義詞
  • unofficial

    spoken widely but not chosen by the government

文法句型

official + language / currency / name

用法筆記

Always attributive. Modified noun is a small set: language, currency, name, anthem, residence, religion, holiday. Differs from sense 2 (AUTHORIZED): here the noun is something a state formally adopts as the standard one for the country.

常見錯誤

French is official in Quebec.
French is the official language of Quebec.
💡keep the modified noun; bare 'official' sounds incomplete.
