What does bulldozer mean?
A bulldozer is a heavy piece of construction equipment consisting of a large tracked tractor fitted with a broad, flat steel blade at the front. It is used to push soil, sand, rubble, or snow, clear vegetation, and demolish buildings, making it one of the most recognizable machines on any major building or roadworks site. The word also has a figurative use: a 'bulldozer' can describe a forceful, relentless person who sweeps aside opposition to get what they want. The term arose in 1870s America from the slang phrase 'bull-dose,' meaning to administer a punishment severe enough for a bull—that is, a savage beating—and it soon came to describe both coercive force and the machine that embodies it. Today the word appears constantly in news coverage of development projects and land disputes, where bulldozers often symbolize unstoppable, impersonal progress.

Etymology of bulldozer
The word originated in 1870s American English, derived from the earlier slang term 'bull-dose,' which meant a severe flogging or beating—a 'dose' harsh enough for a bull. The verb 'to bulldoze' initially meant to intimidate by violence or threats, and by around the 1880s the noun had been applied to the powerful new earth-moving machines whose action of relentlessly pushing everything aside seemed to match the spirit of the original word. The element 'dose' traces back through Latin 'dosis' to Greek 'dosis,' meaning 'a giving,' which also underlies the ordinary English words 'dose' and 'dosage.'
