1.verbtransitiveB2

to take the first step in setting a process, plan, or activity in motion — for example, starting an investigation, launching a project, or opening a conversation with someone new.

Example

The government initiated an official investigation into the data breach at the hospital.

initiate + investigation (formal/official context)

Aarav initiated a weekly book club after realising his coworkers wanted to read more.

Common collocations
  • initiate a process
  • initiate an investigation
  • initiate a project
  • initiate proceedings
  • initiate a conversation
Synonyms
  • begin

    More general and less formal than 'initiate'; can be used for any starting point

  • launch

    Often used for products, campaigns, or big projects; implies a more dramatic public start

  • start

    The most common, neutral alternative; works in both formal and casual settings

Antonyms
  • end

    The opposite of any process that has a beginning and an end

  • conclude

    More formal than 'end', often used in official or procedural contexts

Grammar Patterns

initiate + noun phrase (a process, project, investigation, etc.)

Usage Note

Frequently used in formal or official writing — subjects are often organisations (governments, companies, committees) rather than individuals. Less formal alternatives include 'start' or 'launch'.

Common Mistakes

We initiated the meeting at 2 pm.
We started the meeting at 2 pm.
'initiate' suggests beginning a new process or venture, not a routine event like a daily meeting.
She initiated to write a blog.

2.verbtransitiveB2
Definition

to welcome a person into a club or organisation by performing an official ceremony or following a formal process — for example, a secret society inducting new members at a special gathering.

Example

Darius was initiated into the historical society during a ceremony at the old town hall.

passive: be initiated into [group] + ceremony

Each spring the club initiates around thirty new members after a two-month trial period.

Common collocations
  • initiate into
  • be initiated as a member
  • initiate with a ceremony
  • newly initiated members
Synonyms
  • induct

    More formal and often ceremonial; common in military and official settings

  • welcome

    Warmer and less formal; does not imply a formal ceremony

  • admit

    General term for allowing entry; less ritualistic than 'initiate'

Antonyms
  • expel

    The formal opposite — to force someone to leave a group

  • exclude

    To keep someone from joining in the first place

Grammar Patterns

be initiated into + group / society / organisation

Usage Note

Almost always takes 'into' when followed by the group name. The passive construction ('was initiated') is extremely common. Distinguish from verb sense 1 (START / BEGIN): in this sense the object is a person, not a thing or process.

Common Mistakes

He was initiated as a lawyer after passing the bar.
He was admitted to the bar after passing the exam.
'initiated' is used for membership in groups with a ceremony or special knowledge, not for professional licensing.
She initiated the club last year.
She started the club last year.
When the object is an organisation, use sense 1 (START / BEGIN), not this sense.

Synonym discussion

Sense: verb/1

All four words mean roughly 'to cause something to begin', but they differ in formality, scope, and typical contexts. 'Begin' is the most neutral and widely used — it works for everyday actions ('begin reading', 'begin the meal') as well as formal ones. 'Start' is slightly more informal and can imply a sudden or energetic beginning ('start the car', 'start a fight'). 'Initiate' is more deliberate and procedural: you initiate a project, an investigation, or a formal process, not a routine task. 'Launch' adds drama and visibility — products, campaigns, and organisations are launched with a public announcement. 'Commence' is the most formal, found in legal, academic, and ceremonial writing ('the ceremony will commence at noon'). In everyday speech, 'begin' or 'start' is the natural choice; in a business report or official document, 'initiate' suggests a structured beginning with defined steps.

Etymology

LatinFrenchEnglish

The word 'initiate' comes from Latin 'initiatus', the past participle of 'initiare', meaning 'to begin' or 'to initiate'. That verb in turn comes from 'initium' ('a beginning'), which was formed from 'inire' — literally 'to go into', from 'in-' ('in, into') plus 'ire' ('to go'). The sense of formally admitting someone into a group developed from the idea of letting them 'go into' a society or body of knowledge. English adopted the word in the early 17th century, and both the 'begin' and 'admit to a group' meanings have been present from the start.
