1.adjectiveB1
Definition

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.

Example

Common collocations
  • formal complaint
  • formal agreement
  • formal meeting
  • formal announcement
  • formal request
  • formal written
Synonyms
  • 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

Antonyms
  • unofficial

    describes something done without formal authority or recognition

Usage Note

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

Common Mistakes

I made a formal apologize to her.
I made a formal apology to her.
'apology' is the noun form needed after 'formal', not 'apologize'.
The company gave him a formal warning letter.

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

2.adjectiveB2
Definition

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.

Example

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

The union and management reached a formal agreement on wages, yet little changed on the factory floor.

Common collocations
  • formal head
  • formal leader
  • formal owner
  • formal policy
Synonyms
  • nominal

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

  • titular

    refers specifically to holding a title without the corresponding duties

Antonyms
  • actual

    describes what is real and true rather than just a title

  • real

    emphasises the genuine situation as opposed to the formal one

Usage Note

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. suitable for important or official situations where people follow rules of corre

3.adjectiveA2
Definition

suitable for important or official situations where people follow rules of correct behaviour and appearance — for example, formal clothes for a wedding, or formal language in a job interview.

Example

collocation: formal dress

  • casual

    used especially for clothing and social situations

Usage Note

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.

Common Mistakes

I wore a formal dress to the beach party.
I wore a casual dress to the beach party.
'formal' describes serious, elegant occasions, not relaxed events.

5. arranged in a planned, regular pattern with clear lines and symmetry rather than

Synonym discussion

Sense: adjective/3

Formal is the broadest of these words and describes behaviour, language, dress, or events that follow accepted rules for serious or important situations. Official is narrower — it refers specifically to something approved by an authority (a government, company, or organization) and often involves documents or decisions: an official statement from the mayor, but a formal greeting at a wedding. Proper focuses on what is socially correct or appropriate, but can apply to everyday situations too (proper table manners). Ceremonial is the most specific, describing actions or objects used in a ceremony (a ceremonial sword, a ceremonial role). For clothes, formal wear (suits, gowns) is distinct from ceremonial robes. For language, formal English avoids contractions and slang, while official language appears in laws and contracts.

Etymology

LatinOld FrenchEnglish

Formal comes from Latin formalis, meaning 'relating to form or shape', from forma 'form, shape, appearance'. The word entered English through Old French formal in the 14th century. Its earliest meanings were about following proper procedures and rules — the idea of 'outward shape' evolved into 'following the accepted form'. The sense of 'in name only' (sense 2) developed in the 16th century, contrasting the outer form with the inner reality. The noun meaning 'a formal dance' appeared in American English in the early 1900s.
