1.形容詞B1
釋義

done or arranged by an authority or organization in a public way that follows set rules — for example, a formal complaint made to a company or a formal agreement signed by both sides.

例句

The company received a formal complaint about the noise from the factory.

collocation: formal complaint

同義詞
  • official

    stronger focus on authority; an official statement comes from a person in power

  • authorized

    emphasises permission from a higher body; more limited in scope

反義詞
  • unofficial

    describes something done without formal authority or recognition

用法筆記

Commonly appears before nouns such as complaint, agreement, meeting, announcement, and request. These nouns name actions or documents that need an official process.

💡'apology' is the noun form needed after 'formal', not 'apologize'.

💡'warning' already covers the idea; 'warning letter' is fine but often redundant.

used to describe something that exists in official documents or by title only, without matching what actually happens in practice — for example, a formal leader whose real power belongs to someone else.

pattern: formal + role title (formal head / formal leader)

同義詞
  • nominal

    more formal and less common; used in official or legal contexts

  • titular

    refers specifically to holding a title without the corresponding duties

反義詞
  • actual

    describes what is real and true rather than just a title

  • real

    emphasises the genuine situation as opposed to the formal one

用法筆記

Frequently paired with role titles (formal head, formal leader, formal owner). Adding a clause with 'but', 'yet', or 'though' that contrasts the real situation is the most common pattern.

3.形容詞A2
釋義

The most concrete sense of formal — learners encounter it first with clothes (formal dress, formal suit) and events (formal dinner, formal wedding). The opposite informal is very common at this level too.

常見錯誤

I wore a casual dress to the beach party.
