Halloween brings many fun traditions, but some phrases can cause surprising spelling confusion. One example is “trunk or treats.” Is that the correct phrase, or should you say “trunk or treat”?
If you have seen schools, churches, neighborhoods, or community groups advertise a Halloween event, you may have noticed both forms. This makes people wonder whether “trunk or treat” and “trunk or treats” describe different activities.
The quick answer is simple: “trunk or treat” is the standard form for the Halloween event. It describes an organized activity where children go from decorated car to decorated car to collect candy. The event is usually held in a parking lot rather than from house to house.
The plural-looking “trunk or treats” sometimes appears in casual writing, advertisements, or social media. However, it is not normally the preferred name of the event.
In this guide, you will learn the meaning, origin, spelling, British and American English differences, common mistakes, everyday examples, and search trends surrounding trunk or treats.
Trunk or Treats – Quick Answer
The standard name is trunk or treat, not trunk or treats.
Trunk or treat is a Halloween event where children collect candy from decorated car trunks. Families usually gather in a parking lot, and each participating vehicle becomes a candy stop.
Example
Our school is hosting a trunk or treat on Friday evening.
Another example:
We are decorating our car for the annual trunk or treat.
The phrase is modeled on trick or treat. The main difference is where children collect their candy:
- Trick or treat: children visit homes.
- Trunk or treat: children visit decorated vehicles.
- Trunk or treats: informal variation that is sometimes used, but it is less standard.
The phrase trunk or treat can also be written trunk-or-treat, especially when it works as a compound modifier, such as “a trunk-or-treat event.” Major references use both “trunk-or-treat” and “trunk-or-treating” for the activity.
The Origin of Trunk or Treats
The expression trunk or treat is a modern Halloween phrase based on the older expression trick or treat.
The word trunk refers to the storage compartment at the rear of a car in American English. The word treat refers to something enjoyable given to someone, especially candy during Halloween.
The activity developed in the United States during the 1990s. Its exact creator is not known. Historical accounts indicate that churches and community groups helped develop trunk-or-treat events as an alternative to traditional door-to-door trick-or-treating.
The idea is simple:
House → House → House
becomes:
Car trunk → Car trunk → Car trunk
Participants meet in one central location, decorate their vehicles, and hand out candy to children. Over time, schools, churches, community organizations, and other groups began organizing these events.
Why Is It Called Trunk or Treat?
The name is a playful variation of trick or treat.
Traditional Halloween:
“Trick or treat!”
Trunk-or-treat version:
“Trunk or treat!”
The phrase highlights the most important difference: children receive treats from vehicle trunks rather than from individual houses.
The term trunk or treating is also used for the activity itself. Wiktionary, for example, lists “trunk or treat” as a noun and “trunk or treat” as a verb describing participation in the activity.
British English vs American English Spelling
The phrase is strongly associated with American English and North American Halloween culture.
The biggest vocabulary difference is the word trunk.
| Feature | American English | British English |
|---|---|---|
| Rear car storage | trunk | boot |
| Common event name | trunk or treat | trunk or treat when referring to the American event |
| Hyphenated form | trunk-or-treat | trunk-or-treat may be understood |
| Activity | trunk-or-treating | trunk-or-treating |
| Alternative British wording | — | community Halloween event |
In American English, trunk means the enclosed storage space at the back of a car.
In British English, the usual word is boot.
However, this does not mean you should change the event name to “boot or treat.” That expression is not the established name of the tradition.
For example:
American English: The church is hosting a trunk or treat.
For a British audience, you could explain the phrase:
A trunk or treat is an American-style Halloween event where children collect sweets from decorated car trunks.
This gives readers enough context without changing the established name.
Which Spelling Should You Use?
For most situations, use trunk or treat.
For American Readers
Use:
trunk or treat
Example:
The community center will host a trunk or treat on October 31.
This is the clearest choice for American audiences.
For UK and Commonwealth Readers
You can still use trunk or treat when discussing the American tradition. Because “trunk” is less common in British English, add a short explanation if your audience may not know the term.
For example:
Trunk or treat is an American Halloween event where children collect sweets from decorated cars.
For a Global Audience
The safest approach is to use the standard phrase and explain it once.
For example:
Trunk or treat is a Halloween event where children go from car to car collecting candy from decorated trunks.
This avoids confusion and makes the article understandable to international readers.

The tradition developed in the United States during the 1990s and became increasingly popular as an alternative to traditional door-to-door trick-or-treating.
