  • establish a school / university
  • establish a fund
  • establish a committee
  • establish a system
  • establish a network
Synonyms
  • found

  • set up

    more informal; used for everyday situations like starting a small business or system ('set up a blog', 'set up a meeting')

  • create

    broader in meaning; implies bringing something into existence but does not carry the sense of long-term continuity

Antonyms

Grammar Patterns

establish + noun (business / organisation / system)

Common Mistakes

The company was established in 2020 by two friends.
The company was founded in 2020 by two friends.
'found' is more common for the very first creation of a company; 'establish' works but sounds slightly formal in everyday speech.

2. To start a formal connection — such as a working relationship or diplomatic ties

2.verbtransitiveB2
Definition

To start a formal connection — such as a working relationship or diplomatic ties — between yourself and another person, organisation, or country, for example by opening talks or making contact with a new business partner.

Example

Tara established a close working relationship with the Japanese supplier.

establish + relationship / connection

The two countries established diplomatic ties in 1992 after years of conflict.

Common collocations
  • establish a relationship
  • establish ties
  • establish contact
  • establish links
  • establish communication
  • establish diplomatic relations
  • establish a connection
Synonyms
  • set up

    less formal; 'set up a meeting' vs 'establish contact'; 'set up' works for practical arrangements, 'establish' for durable relationships

  • forge

    stronger connotation of effort and difficulty; 'forge an alliance' implies overcoming obstacles

  • form

    neutral and broad; 'form a partnership' can be used anywhere 'establish a partnership' appears, but sounds less official

Antonyms
  • break off

    to end a relationship or communication suddenly

  • sever

    to cut ties or connections completely, usually formally

Grammar Patterns

establish + noun (relationship / ties / contact / links)

Usage Note

Common objects include relationship, contact, ties, links, and communication — always referring to the beginning point of the connection. Once a relationship is established, you maintain or strengthen it, not re-establish it (unless it was broken first).

Common Mistakes

We established a friendship with them very quickly.' (when meeting organically)
We struck up a friendship with them very quickly.
'establish a friendship' sounds too formal for casual personal friendships; use 'strike up' or 'develop' instead.

3. To cause yourself, an idea, a rule, or a practice to become recognised, accepted

3.verbtransitiveB2
Definition

To cause yourself, an idea, a rule, or a practice to become recognised, accepted, and respected by others in a particular setting — for example, proving your reliability to colleagues, or making a habit widely followed within a group.

Example

It took Ilan several months to establish himself as a reliable member of the team.

establish + reflexive pronoun + as [role]

The coach established a tradition of team breakfasts before every match.

Common collocations
  • establish yourself as
  • establish a reputation
  • establish trust
  • establish credibility
  • establish authority
  • establish a routine
  • establish a custom
  • establish a rule
Synonyms
  • build

    emphasises the gradual process; 'build a reputation' suggests step-by-step effort, while 'establish a reputation' emphasises the final result of being accepted

  • secure

    suggests gaining something after effort or competition; 'secure someone's trust' implies it was not easy to earn

  • earn

    focuses on deserving recognition through one's actions; 'earn respect' is more personal and less formal than 'establish oneself as a respected figure'

Antonyms
  • lose

    to no longer have the trust, respect, or acceptance one once had

  • undermine

    to gradually weaken someone's position, reputation, or authority

Grammar Patterns

establish + reflexive pronoun + as + noun

establish + noun + as + complement

Usage Note

Frequently used with reflexive pronouns (establish yourself/himself/oneself etc.) followed by as to indicate a role or position that the person has earned recognition for. When the object is an abstract thing (reputation, rule, custom), the implication is that it became standard through consistent effort over time.

Common Mistakes

She established her reputation overnight.
She built her reputation over several years.
'establish' implies a process that takes time and effort; 'build' is more natural for gradual reputation growth, though 'establish' is possible in formal writing.

4. To reach and keep a stable, successful position in a particular setting, profess

4.verbtransitiveC1
Definition

To reach and keep a stable, successful position in a particular setting, profession, or market after investing time and effort — for example, a new restaurant winning regular customers, or a professional gaining respect in their field over years of work.

Example

After five years of hard work, the restaurant had established itself as a local favourite.

establish + itself + as [achieved position]

Pim established himself among the top chess players in the country.

Common collocations
  • establish yourself
  • establish itself
  • establish a presence
  • establish a foothold
  • establish a position
  • establish oneself as a leader
Synonyms
  • secure

    focuses on gaining a position firmly; 'secure a foothold in the market' emphasises protecting what you gained, not just reaching it

  • settle

    softer and less ambitious; 'settle into a new job' implies comfort, not necessarily competitive success

  • entrench

    stronger and can sound negative; 'entrenched interests' implies a position so fixed it resists change

Grammar Patterns

establish + reflexive pronoun + as + noun (position)

establish + itself

Usage Note

Almost always used with a reflexive pronoun (itself, yourself, himself, etc.) or a reference to position (presence, foothold, standing). Distinguish from sense 3: sense 3 is about being accepted as a certain kind of person; sense 4 is about occupying a successful position, often competitively.

5. To prove that something is true by discovering facts, evidence, or reasons that

5.verbtransitiveC1
Definition

To prove that something is true by discovering facts, evidence, or reasons that confirm it beyond reasonable doubt — for example, detectives showing who committed a crime, or researchers demonstrating a cause-and-effect relationship through experiments.

Example

Police established that the suspect was at the scene during the robbery.

establish + that-clause for proving facts

Scientists have established a clear connection between air pollution and respiratory illness.

Common collocations
  • establish a fact
  • establish the truth
  • establish the cause of
  • establish guilt / innocence
  • establish a link
  • establish a connection
  • establish that
Synonyms
  • prove

    the closest synonym; 'prove' is less formal and more common in everyday speech; 'establish' implies a more thorough, systematic verification

  • determine

    focuses on the investigative process of finding the answer; 'determine the cause' suggests careful analysis rather than providing proof to others

  • confirm

    implies that something was already suspected or partially known; 'confirm the results' means checking that what you expected is true

  • verify

    focuses on checking accuracy against a standard; 'verify an identity' means checking documents match the person

Antonyms
  • disprove

    to show that a claim or theory is false through evidence

  • refute

    to prove a statement or argument is wrong, typically in formal debate or scientific contexts

Grammar Patterns

establish + that-clause

establish + noun + as + complement

Usage Note

The only sense that regularly takes a that-clause to state the conclusion reached. This sense is formal and typical of legal, scientific, and journalistic contexts. In everyday conversation, 'prove' or 'find out' are more natural substitutes.

Common Mistakes

I established that she was lying.' (in a casual argument)
I figured out that she was lying.
'establish' sounds too formal for everyday disagreements; use 'prove' (formal but not legal) or 'find out' / 'figure out' (informal).

Synonym discussion

Sense: verb/1

These four verbs all describe bringing something new into existence, but they differ in formality, scale, and emphasis. 'Found' is the most formal and is reserved for institutions, cities, or significant organisations ('The university was founded in 1892'); it emphasises the very first act of creation. 'Set up' is the most informal and practical — you set up a tent, a website, a meeting, or a small business; it focuses on the physical or logistical arrangement rather than long-term continuity. 'Create' is the broadest: anything that is made can be created, from a painting to a new law; it does not carry the sense of durability that 'establish' does. 'Launch' adds a public dimension — it suggests a deliberate unveiling or debut, often for products, campaigns, or initiatives ('The company launched its new app last month'). Use 'establish' when you want to stress that the thing you start is meant to last and operate over time, as in founding a lasting institution or system. For example: 'She established a scholarship fund that still runs today' (long-term) vs 'She set up a temporary fund for the disaster relief' (short-term, practical).

Etymology

LatinFrenchEnglish

The word 'establish' entered English from Old French 'establir', which came from Latin 'stabilire' — meaning 'to make stable or firm'. The Latin root 'stabilis' (stable, firm, steady) is also the source of 'stable', 'stability', and 'state'. This core idea of 'making something firm so it lasts' runs through every modern sense of the word, whether you are founding a company (making it stable over time), building a relationship (making a connection firm), or proving a fact (making an argument unshakeable).
