bulldozer

/ˌbʊlˈdoʊzər/

/ˈbʊldəʊzə/

Other forms: bulldozers

A bulldozer is a large truck with a wide blade that can dig and push dirt and debris. You'll often see a bulldozer among the vehicles on a construction site.

Although many people have a tendency to call any giant truck a bulldozer, it's actually a specific kind of tractor with a blade called a "dozer blade" at the front and a big claw, or "ripper" at the back. A bulldozer can run over any rubble or trash and clear it away — this ability led to the slang meaning of the word, "powerful, intimidating person."
