IPA: /ˈtrʌkfəl/
KK: /trʌkˌfʊl/
The amount of goods or materials that can be carried in a truck.
We need a truckful of supplies for the event.
Truckful → It is formed from "truck" (from Middle English *troch*, meaning a cart or a small vehicle) and "-ful" (meaning full of). The word "truckful" means full of trucks or the amount that a truck can carry.
Think of a truck being 'full of' something — that's what truckful means.
