attributive: official + duties / role / capacity

Common collocations
  • official duties
  • official capacity
  • official role
  • official business
Synonyms
  • professional

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

  • work-related

    neutral, no implication of public authority

Antonyms
  • personal

    private life rather than job-related

  • private

    outside one's role or position

Grammar Patterns

official + noun (duties, capacity, role)

Usage Note

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.

Common Mistakes

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.adjectiveB2
Definition

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.

Example

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.

Common collocations
  • official ceremony
  • official visit
  • official complaint
  • official ban
  • official statement
Synonyms
  • 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

Antonyms
  • unofficial

    lacking the approval of an authority

  • informal

    outside set procedures, often friendly

Grammar Patterns

official + noun

be + official

Usage Note

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.

Common Mistakes

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.adjectiveC2
Definition

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

Example

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.

Common collocations

  • make it official
  • the official result
  • the official announcement
Synonyms
  • confirmed

    neutral; doesn't imply a public authority

  • public

    stresses that the news is now widely known

Antonyms
  • unofficial

    not yet publicly confirmed; rumoured

  • rumoured

    talked about but not yet announced as fact

Grammar Patterns

it's official (that-clause)

make + something + official

Usage Note

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.

Common Mistakes

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.

Common collocations
  • official language
  • official currency
  • official name
  • official anthem
  • official religion
Synonyms
  • national

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

  • state

    as in 'state language', stresses government adoption

Antonyms
  • unofficial

    spoken widely but not chosen by the government

Grammar Patterns

official + language / currency / name

Usage Note

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.

Common Mistakes

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

Used to say that something is now formally announced or confirmed, even if it was already obvious.

Synonym discussion

Sense: noun/1

All four words name someone with authority inside an organization, but they differ in scope and tone. 'Official' is the broadest and most neutral: any decision-making post in a government, party, or large body — for example a customs official or a UN official. 'Officer' is narrower; it tends to mean a specific named post, especially in the police, military, or on a board (chief financial officer, police officer). 'Administrator' stresses the running and managing side rather than authority itself; a hospital administrator handles staff and budgets but may not set policy. 'Bureaucrat' carries clearly negative weight, suggesting someone who hides behind paperwork and slow procedures: 'The grant was lost because some bureaucrat in head office mislaid the form.' Pick 'official' when you simply mean a person in a public post; switch to 'officer' for a named title, 'administrator' for a manager, or 'bureaucrat' only when you want to complain.

Etymology

LatinLate LatinOld FrenchMiddle EnglishModern English

The word entered English in the late 1300s from Old French 'official', which had been borrowed from Late Latin 'officialis'. In Latin it first worked as an adjective meaning 'belonging to a duty or service' and was built on 'officium' (a duty, a service, an office), itself a contraction of 'opificium' — the doing of work, from 'opus' (work) plus 'facere' (to do). The earliest English use was as a noun for a church or court attendant; the adjective sense 'authorized by a body in charge' grew out of this and became dominant only in the 1600s. The modern sporting sense (a referee or umpire) is a much later American specialization from the late 1800s.
