Correct:

Incorrect:
- Movie trailor
- Travel trailor
- Cargo trailor
Although many people accidentally write “trailor,” especially because English pronunciation can be confusing, the accepted and proper form is always trailer.
What Does “Trailer” Mean?
The word trailer has several meanings depending on the context. In general, it refers to something that follows behind something else.
Common Meanings of Trailer

Why Do People Spell Trailer as “Trailor”?
The confusion between trailor vs trailer mainly comes from pronunciation.
In spoken English, “trailer” sounds very similar to words ending in “-or,” such as:
- sailor
- tailor
- actor
Because of this, many people naturally assume the spelling should be “trailor.” However, English spelling doesn’t always follow pronunciation patterns consistently.
Another reason is simple typing habits and autocorrect errors. Since “trailor” looks believable, many people don’t realize it’s incorrect.
Origin of the Word “Trailer”
The word trailer comes from the verb “trail,” which means:
- to follow behind
- to drag along
The suffix “-er” is added to show something that performs an action or follows something else.
So, a trailer literally means:
“something that trails behind.”
This explains why the term works for both vehicles and movie previews:
- A cargo trailer follows a truck.
- A movie trailer comes before and promotes the main film.
