Quick Answer

The correct choice depends on how you use the words.

Kick off = Verb (phrasal verb) → to begin or start something.
Kickoff = Noun or adjective → the beginning of an event, meeting, project, campaign, or sports game.

Form	Part of Speech	Correct Usage	Example
Kick off	Verb	✅ Yes	We will kick off the meeting at 9 a.m.
Kickoff	Noun	✅ Yes	The project kickoff is tomorrow.
Kickoff	Adjective	✅ Yes	We attended the kickoff meeting.

Examples

✅ Let’s kick off the discussion with introductions.
✅ The kickoff meeting starts at 10 a.m.

❌ Let’s kickoff the meeting.

A simple rule is to use kick off when describing an action and kickoff when referring to an event, meeting, or starting point.

The Origin of Kick Off or Kickoff

The phrase kick off originated in sports, especially football (soccer) and American football, where it literally means kicking the ball to begin a game. Over time, English speakers started using the expression figuratively to mean beginning any activity or event.

As business and project management language evolved, kickoff became a closed compound word used as a noun or adjective. Today, it commonly refers to the official start of a project, campaign, conference, or team meeting.

Major dictionaries such as Merriam-Webster, Cambridge Dictionary, Oxford English Dictionary, Collins Dictionary, and Macmillan Dictionary recognize both forms. The difference is based on grammar, not spelling preference.

Examples:

We will kick off the conference with a welcome speech. (verb)
The project kickoff is scheduled for Monday. (noun)
Everyone attended the kickoff meeting. (adjective)

British English vs American English Spelling

Unlike words such as colour/color or centre/center, there is no spelling difference between British English and American English for kick off and kickoff.

Both varieties follow the same grammar rule:

Kick off = verb (action)
Kickoff = noun or adjective (event or description)

Whether you write for readers in the United Kingdom, United States, Canada, Australia, or other English-speaking countries, the rule remains exactly the same.

Pronunciation of Kick Off or Kickoff

Both kick off and kickoff have the same pronunciation. The difference is found only in grammar and word usage, not in spoken English.

IPA Pronunciation

British English: /ˌkɪk ˈɒf/
American English: /ˌkɪk ˈɔːf/

Simple Pronunciation

Kick off / Kickoff → KIK OFF

Because they sound identical, many English learners accidentally choose the wrong spelling when writing.

Although pronunciation never changes, choosing the correct written form is important in professional writing, business communication, and academic writing.

Why People Confuse Kick Off or Kickoff

Many writers confuse kick off and kickoff because they have the same pronunciation and nearly the same meaning.

Here are the most common reasons:

Both forms sound exactly the same.
People do not know the difference between a phrasal verb and a compound noun.
Business professionals often use the term kickoff meeting, while speakers say kick off the meeting.
Writers combine the words when they should be separate.
Fast typing and auto-correct may not detect the grammar mistake.

This confusion appears in many situations, including:

Project kickoff
Kickoff meeting
Kickoff presentation
Kickoff event
Campaign kickoff
Product kickoff
Team kickoff

These are all noun or adjective uses.

However:

Kick off the meeting.
Kick off the project.
Kick off the discussion.
Kick off the conference.
Kick off the event.

These are verb uses because they describe an action.

A simple grammar check helps:

If someone is doing the action, use kick off.
If you are naming the beginning of something, use kickoff.

Which Spelling Should You Use?

The correct spelling depends on the part of speech, not on whether you are writing in British English or American English.

Use kick off when it is a verb (phrasal verb).
Use kickoff when it is a noun or an adjective.

This rule is accepted in Standard English, major English dictionaries, and popular style guides.

If You Are Writing in American English

Use:

✅ We will kick off the presentation at 10 a.m.
✅ The project kickoff is scheduled for Monday.

Avoid:

❌ We will kickoff the presentation.

If You Are Writing in British English

The same grammar rule applies.

Use:

✅ Let’s kick off the conference.
✅ The kickoff meeting starts at noon.

If You Write for a Global Audience

Whether your readers are in the United States, United Kingdom, Canada, Australia, India, or elsewhere, use the grammar rule instead of guessing.
