Many people mix up trailer and trailor because they sound the same. The correct spelling is always trailer. It is used for a towed vehicle or a short movie preview, and writing it right avoids mistakes.
The word trailer comes from the verb “to trail,” which means to follow behind. Using trailer instead of trailor helps your writing stay clear. Remembering the trail link makes spelling easy and strengthens your English skills.
You can see trailer in many sentences. A cargo trailer carries goods, a movie trailer shows short clips, and a trailer home provides living space. Always use trailer with -er, never trailor, for correct English writing.
