IPA: //ˈsɛmɪˌtreɪlər//
KK: /ˈsɛmɪˌtreɪlər/
A type of trailer that has wheels only at the back and is supported at the front by a truck or towing vehicle.
The truck driver loaded the goods onto the semitrailer before hitting the road.
**Semitrailer** → It is formed from "semi-" (meaning half) and "trailer" (from the verb "trail" meaning to pull or drag). A semitrailer is a trailer that is only half supported by a vehicle, as it is designed to be towed by a truck, with the front part resting on the truck's chassis.
Think of 'semi-' meaning half, and 'trailer' as something that is pulled. This helps you remember that a semitrailer is a type of trailer that is only half supported by the towing vehicle.
